Bob, are you aware of the Wichita Mountains up in Oklahoma? There really is some world-class climbing up there and the hiking, scenery, wildlife and wilderness is also world-class. I had a four year exile in Dallas for gradschool and I found the Wichitas during my second semester there. After that, I can't tell you how many times I went. It was my little mountain refuge while stuck in the big city. I know it is a bit further from Austin than Dallas, but on weekends, you will be hard-pressed to do better. It is spectacular!
