I'm also in San Antonio and while I do have a handful of crunchy friends, I've seen like 2 babywearers all year. I have connected w/ other crunchy SA moms, though, on some other forums and now on my FB.
I'll be moving to an even less-crunchy area, though, at the end of October... I'm nervous.
I've gotten a very positive response, though, to my babywearing, in San Antonio and in WV.
