I am not usually that free to cruise much anymore, as I usually have my 3 year old daughter with me. It would be great to plan some trail rides. I sold my 01 TJ 3 years ago, and just bought an 05 TJ, so I am ready to get back on the trails soon!
The only place I know that is close to austin is Hidden Falls Adventure park out in Marble Falls. I believe Llano has a few places too(katemcy, etc..). The best place I've been is North of Tyler in Gilmer, Barnwell Mountain off road park. Has something for everyone. About 2 1/2 hours by Hunstville is General Sams.
The guys at Jeep Masters also get together for trail rides too
