Reflection on the Field

No field work this week, the LiCor has been sent back to get fixed and recalibrated, but I had a couple of thoughts and one question on working in the field and with RA.

Question first. If it hurts RA's manly pride for me to carry heavy things or swing the machete then I'm not going to argue with him. I'll offer to do it but I'm not going to insist, it seems silly to make more work for myself and fight for it. Should I be more insistent? Am I not being feminist enough?

Most of my thoughts center on RA's apparent lousy sense of direction. When I said we needed to go a little further west for on collar and he said "I'm so turned around I have no idea where that is" I was a bit flabbergasted; west was heading towards the highway, which you could hear, also not up or down hill and we hadn't even been winding around much. He was pretty tired by then, so that was part of the problem. I'm sure he can get around with a compass; I've been with him when he was using one and I fairly sure orienteering is taught in [home country]'s army (otherwise navigating in areas without roads is much more difficult). I'm not sure if normally his sense of direction is as bad as it was out at the site or if it was a related to exhaustion, terrain, and/or not pay attention because that's what I was doing.

One of the few things I'm really good at* is visualizing in 3D. This is helpful for my job and some puzzles and I think it's why I my sense of direction isn't too bad. Drive me around for a while, stick me in the woods and I might guess north right 30% of the time (it'd be 25% of the time except when the sun is low(ish) in the sky I can get E or W, then turn 90°) but if I have a starting point, like I know the road runs generally N/S and I need to move due E to find a point (like what I was doing while placing collars) I can do it, or if I need a get back to a starting point I don't have retrace all my steps. It's like I map the route (detours around trees, thickets,... and/or from point to point) in my head, along with the lay of the land.

I used to be able to figure out what direction north (E, W, or S) most places around where I lived because most of the roads were fairly straight, for that matter I probably still can. They weren't in a grid pattern (except in DC, which was way outside my mental map anyway) but they were mostly straight. I knew which way, generally, my house faced (east) and could back track from where I was to home and figure out the cardinals. Things outside this map were connected by a much looser, cardinal-direction wise, road "network" of how you got places (like, route 7 runs through here, route 50 will take you to x and y) which could connect two destinations but not necessarily given you an idea of the distances (but possibly travel time) or which way you were going. (It never helped that sometimes to go physically south you went "north" on 495. And I only drove there for a year.)

I mostly have T-town "mapped" as a route network. Near downtown and campus the roads are regular enough that I could actually draw a map and I could include some of the more out lying roads. But when you get out of town a little ways the roads wind around so much that really keeping a clear picture of it in my head is hard, it becomes more of a general this road takes you to these roads or that place. Also there are a lot of parts of town I never drive through, no reason except I've just never needed, so those areas are completely blank in my mental map. I do have a better mental map of where different communities/places are within the county here than I did in Virginia; I think because I deal with maps of the county a lot and because of tornado warnings - I had to learn if a storm moving east near Samantha was going to threaten my house.

Do you guys have mental maps or road networks of where you drive (walk, bike,...) a lot?

A map of my childhood

With long winded explanation.

Chad has a post asking about how far we were allowed to roam as kids. HP (comment #40) suggested you look up your old neighborhood, because he over estimated how far he actually went from home. I over estimated how far away the library was by a little bit - Google says it's 1.7 miles driven miles. The house I grew up in is the blue thumb-tack.


View Larger Map

The library was the farthest place I routinely went without my folks but my brother, some friends, and I would sometimes ride the bike trail a couple of miles out just for the heck of it. One time we rode out to the West Falls Church Metro Station*.

We lived on the corner, while the street we faced (Polly ST) was quiet, Wolftrap RD was a little busy. When I was little (pre-k) Mom would walk me to Christie's house (other side of Wolftrap). Later she'd walk me to across from her road and Mrs. Patrick and Christie would walk to the other side to "meet" us. Sometime around kindergarten or 1st grade Mom started letting me go on my own. Our school bus stop moved over the years but in Kindergarten it was at the end of Christie's street; after the first day, Pat (then a 4th grader) walked me.

As far as playing went, we would usually play in any of several yards (usually back yards). There weren't that many kids on our block so there were only so many places I could have been. I guess Mom knew which house we were at most of the time. Mike's mom would sometimes call our house and tell Mom if she saw him to tell him to put on his shoes. So maybe our mother's didn't always know.

I'm not sure when I started riding my bike places. Certainly by 10, I was riding to the library, 7-11, and drug store. I can remember being sent to People's Drug to tell Pat it was time to come home on a Saturday or in the summer. People's had several video games and he'd spend all afternoon there. I'd also go to the stationery store in the shopping center across the street from there, or the fabric store (more rarely). But, oh, the library - being able to ride their myself = many many happy hours.

In the summer, I'd ride my walk bike to the pool and meet Caroline or go with Pat. Once I joined the swim team, Dad would drive me to practice (@ 7:30am) and then I'd walk home. The summer between 6th and 7th grades, after practice I'd either read or go to the library for most of the day. One summer I babysat a girl (6ish) from around the corner in the mornings. The younger kids practiced at 8:30, so I'd shower and dress at the pool then Lizzie and I would walk to my house.

I used to spend lots of time at the little park on the other side of OLGC (named "Town Park" on Google). In elementary school I organized my friends once to map the stream that ran through it. I sucked at naming things even then. The best name (and only one I can remember now) we came up with was "BR tree". It was pretty big around, easy to hide behind, even if not standing up. Our Irish Setter got a lot of nice long walks in the woods all summer long. I'd walk in the stream sometimes (man the stone bruises I used get!) other times we'd stay on the path then follow the stream up to Echols St and walk home that way. I was always careful to walk really close to the stream so no one would be upset I was in their yard.

Another place we would sometimes wander around were the undeveloped lots at the industrial park. (Mom almost certainly didn't know about that.) A few times in the summer Pat and I went to the playground at Vienna Elementary (near the community center and library) and played tag or had water gun fights on the "play structure". In tag if you touched the gravel you automatically became it; the water gun fights would have to have ceasefires so we could go across the street to Town Hall and refill from the water fountain. There were never as many parents at the park as there were kids. In 8th and 9th grade I sometimes ride up to visit my 6th grade teacher, Rick Wormeli after school.

I marked the pond at the country club because we skated there a few times one winter. Until a guy came by and told us the pond had been deepened the last summer from 4 feet to 10 feet. Suddenly we could all her our mothers calling. The idea of falling into 4 feet of water didn't seem nearly as scary as falling through into 10 feet of ice cold water. Who knows if it was true but it got gone.

I often wish Nettie didn't live some far out and on a busy-ish road. Our road is too narrow, windy, and crazy drive filled for her to even ride her bike on it and there's only one kid her age in walking distance (directly across the street, actually). Another of her friends may move out our way, her family's looked at a couple of houses with in a mile of M&D's. Maybe Nettie will become a little more brave about walking along the road if she has somewhere to go.


*By the time we got back to where we got on the roads (about a mile from home) I didn't think I'd make it but Pat pointed out that I kind of had to. When we got home I was hot, thirsty, and exhausted. I poured a glass of kool-aid, sat down, drank it down, and promptly vomited it back up on the family room rug. The first and last time I made that mistake!

Where I've been

These are all the states I've visited.

visited 27 states (54%)

These are all the states I've been in (as best I can tell):

visited 33 states (66%)

Apparently I've been avoiding Kentuck. I may get to add Oregon this year, if I can come up with a paper/poster. I'm not going to do a countries I've visited map because it would be embarrassing (US, Canada, England (ok, Heathrow Airport), and Scotland).

Anybody Seen Noah?

A comment on Whatever sent me to look at the flood map for where I live. As I'd already figured out, Noah will be floating by before my house floods. Well, maybe my house will flood but my parents live on top of the hill so the animals and I can just walk over there.

My house (and my parents for that matter) is in a X zone. On the map there are two X zones. Definition one is "areas of 500-year flood; areas of 100-year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 100-year floods." Definition two is "areas determined to be outside 500-year floodplain. I'm definitely not behind a levee; any of the others could apply but I don't think I live in a 100-year floodplain. What I found most interesting was the existence of two definitions for zone X.

The viewable map is a scan of a black and white map. Therefore, I choose to assume there is some stippling or light grey color, not picked up by the scanner, that would show which of the two zone Xs an area is, but why not pick another letter for one of them. As one who makes maps as part of my job, this is bad map making. I was taught to make labels, names, colors, etc. distinct. At least as much as possible, sometimes historical uses or names limit one. I was also taught to keep in mind reproducibility and the possibility that a color map may be printed B&W. It isn't possible to be perfect (too many dash patterns can make one go crazy!) and I don't know how old the actual map is (possibly before color printing or scanning was economic). Maybe the two zone Xs have always been used. If so shame on flood mappers of old (for starting this) and new (for continuing). Yes, in the long run the difference is very small between the designations. But it still an iffy choice.
