Shannon- its out BEYOND the 1604 loop (further NW). Scenic loop road runs from SH16 to grey forest, then eventually meets up with the end of hausman rd (kind of behind frederich park-ish. in the hills behind there) at a T intersection. Scenic Loop rd eventually intersects Boerne Stage rd at the intersection where Scenic Loop Cafe is located. (if you haven't been to the Scenic Loop cafe- go). Boerne stage road then connects with I-10 in leon springs.
here's a map, if it works- not sure if mapquest will replicate the directions.
the area there is still pretty rural. there is one mom and pop mexican restaurant located across from the intersection. there are nice, older residential ranch-type homes across the street and immediately adjacent to the proposed walmart property. There is a protected cave up on the hill behind it that contains protected cave invertebrates. scenic loop road is still a 2-lane windy, residential road (one lane in either direction). Its not developed at all, really- not anything at all like the intersection of Loop 1604 and Bandera Rd. Its actually a really pretty area- worth a quick drive on a nice day. it is SO pretty over there. and fairly quiet.
if you were to take a drive over there, i'd start at the I-10/Boerne Stage Rd intersection (by the HEB in leon springs). follow that to the south/west. when you get to the 4-way intersection (where scenic loop cafe is located) take a left onto Scenic Loop Rd. follow that up and down a few hills. at the stop sign (thats Hausman Rd on the left)- stay straight. after you wind down the hill, that little "town" is Grey Forest. and yes, that is pretty much the entire town. Stay on scenic loop rd. Scenic Loop Rd ends at a stoplight where it intersects SH 16. the property on the right hand corner- mostly a big field with a fireworks stand on the SH16 side- is where the walmart is supposed to go in.
I hope that helps- its one of my favorite areas of "san antonio". Its worth taking a look at- if nothing else, in order to do a "before" and "after" comparison of the effects that a walmart has on a rural area, if walmart ends of coming in. I hope it doesn't.
keep in mind that that intersection is not too very far from fredrich park and the soon to be opened crown ridge natural area, where there are black capped vireos and golden cheeked warblers (both endagered birds), in season.
also keep in mind that if walmart comes in, then most likely, it wont come in alone. it will, at least eventually, draw all sorts of other parasite commercial interests to the immediate area.
