Well if you don't want to get arrested or shot with rock salt, I'd join your local wheeling club, they usually have the skinny on local spots, and permission to wheel on private land.
1994 ZJ, 5.2L/46RH, NP242 & D44HD Swap, 4" SA Lift, 31" KM2s, and all the usual... I only lifted it so I wouldn't have to drive my grandma to church anymore... ;)
Remember: Every time you call a Jeep a "car", God kills a kitten.
