Public quail hunting in Texas. Chaparral WMA (5-6 hour drive from Whos-town) 5 open days a year, you just missed two of them. A small place just north of Chaparral WMA about the same opportunity. Check TPWD public hunting areas, very few within three hours of Whos-town. Choke Canyon has some public hunting for quail, (3.5 - 4 hours) but it's at bit too woodsy for hunting quail.
Just south of Columbus, TX on I-10 @ 1 hour west of Whos-town is a hunting preserve, Top-Flight Hunting. www.topflighthunting.com
Leon's a great guy, quail @ 8$ ea, they also have Chukar and Pheasant, but they are 'flight-conditioned' birds.
