Darn, and I've been birding in Texas a few times, and somehow never had a burger here! In the small towns in South Texas, I recall (if they were large enough to have any restaurants), most towns had a Jack-in-the Box and a Pizza Hut...oh, and maybe a Subway. Guess you have to hit the larger towns?? Super W, nonetheless!
If you say so. I spent a couple of years at Rice (don't ask how long ago), but don't remember these. Maybe it was before their rise to fame.
I also spent a summer in Socorro (before I went to Rice), and remember it as a pleasant sleepy little college town. Enjoy Bosque del Apache.
