Welcome to CORE. Keep an eye out on posts. Groups go out fairly regular. Post up and the group will let you know if the place they're going is friendly to stock/beginners or not. Some are; some aren't. I think the next official run is mid-October to Harlan. I'm planning on that one.
So a new Wrangler meaning 07 or just new to you? Have you done any mods to it yet? Lift/tires? How bout a pic?
I've got an 04 TJ. Right now stock except for a 3" lift sitting on 33x12.50 ProComp M/T (and an extremely fly windshield banner ;) ).
