Spent the past 5 days riding in Big Bend. 1251 square miles of high mountain desert along the Rio Grand. Me and my friend Charlie camped in the Chisos Basin and took day rides thru the mountains and into the desert. The weather was great, We were camped at 5400 feet, 37 F at night and 70's during day. About 10 to 15 deg. warmer in the valley. It's a great place to get away, you can ride all day, sometimes days without ever seeing anyone else, but go Oct thru May. Starting in June it gets way hot reaching well over 100 deg. in the valley. Up in the mountains you'll see black bear, mule deer and mountain lions. Down in the valley , javelina and white tail deer.
