I live in Coppell which is where Bama practiced for the Michigan State game. I just read where 59 schools in the DFW area have indoor practice facilities. Whoa!
My alma mater (Winfield, AL) just built a very nice indoor practice facility especially for a small (4A) school. I don't think it's a full 100 yards. I'll try to post a few pics if I get a chance. I'm sure several 6A-7A schools have them too.
