Looks like lots of great advice. Another idea, visit Alpine and then tour McDonald Observatory and catch a Star Gazing night (check their website). Also a state park at Ft. Davis that has FHU. Due to altitude Alpine will be cooler than BB. From my experience at BB, you will want to hike to a few places--always bring water, a map, and compass. Good hikes start near the Chisos Basin. The road to the Chisos Basin limits trailer length due to twists and turns in the road. If you stop at Seminole Canyon SP, check on the availability to hike to the White Shaman indian pictograph site. Enjoy the trip!
