In particular the area around Big Bend, Alpine, Marfa, Presidio, probably also the Hill country. Has anyone done this who has tips, or who has read the book 25 bicycle tours in the hill country and West Texas (thinking about getting it)? I've been in that area before but it was a long time ago and on a motorcycle one time and in a car another and I didn't camp. Such incredibly pretty country it's never left my imagination. Thinking about maybe the fall to catch the wildflowers.
