Been there a few times, it's pretty cool. Usually on a Sat. or Sun. morning you'll find a few people hanging out in front of the park getting ready to go in. You'd probably be able to hook up with them.
Or on your way south on 206 you'll pass the Pic A Lilly (bar/restaurant) theres usually some Jeeps in the parking lot.
By the way Livvi, it's a Jeep, not a truck, car or anything else. Always refer to it as a Jeep.
Good luck if you hit Wharton. Have fun...
Look at the North Jersey Wheeling Hookup thread, there are usually a few guys going out on Sat or Sun, if you don't mind coming up to North Jersey.
Whats cool about the thread they'll set up a time and place to meet. Just chime in and that way you'll be sure to have someone to wheel with.
