Chris, we'll have to have a get together for those of in North Central Texas when you decide to visit.
Texas Cop, I noticed that you didn't mention North Central Texas!!

Whatsammater with you?!?!?!?!?
Ralph, yeah Dallas is just f'n WONDERFUL in July/Aug time frame IF you like 100+ degree temps and a high relative humidity.

Seahorse, the mountains East of El Paso are fairly nice, but once you get past Van Horn and all the way to Big Springs is pretty much desert. I've driven I-10 to I-20 quite a few times (and on into Dallas)
