Nice stuff. Whereabouts in TX are the Davis Mountains and did you need to use the AC?
Ft Davis is in west Texas just south of Van Horn and north of Big Bend National Park. Air was not necessary when we were there as Ft Davis has a high elevation around 4,000 I believe. Lots of history and don't miss McDonald Observatory with one of world's largest telescopes.
