Only club I know of in Lubbock area is the 4x4 and more club. fwdnut.com. It's a good group of people. We offroad about once a month down in Post. Next run is Sept. 22nd. It will be the last run of the year before the ranch opens up for hunting. You can wheel a stock rig out there. You just have to stay on the less technical trails. I wheeled a few years in a stock TJ. There's plenty of fun to be had even on the easier trails. You will need to have stout recovery points on your rig for if/when you get stuck though.
