Welcome. SMORR is going to be the best (close) place for what it sounds like you like to do. Chadwick is baby stuff compared to what you can get into at SMORR. I'm on the SMORR site and am out there wheeling or goofing off in one way or another quite often. You get ready to go out; let me know. I'd be happy to show you around or get you hooked up with someone else incase I'm not going to be there. Again welcome, and sorry you have to wheel a landrover! Haha just kidding they wheel great.
Also there are other great places to wheel within a reasonable distance... Look at the maps/destination page.
