Hey D2, I don't live out there but am a lease member just outside of Comstock. There are some really cool places to cruise around out there and some of the little towns are really old. I have not yet MD out there anywhere but if you do some research online there are some historic places out there.
Seminol Canyon has a bunch of pictographs and such and Lake Amistad is a very clear nice Lake (big to).
Good luck out there -
