Great suggestions, all!
Out of curiosity, do the U.S. Calvary sites have a place on the web? We're working a HUGE book on the Army, over the next 2 years or so, and that might be an interesting diversion as well. Depending on what they have there, it might even warrant an extra night's stay.
The area has always had such a reputation for artists and photographers that I'm excited to spend a few days there, even if most of it is scripted.
Thanks!
