In the small town of Pennsville, NJ there is a great place to go off roading if you don't want to be extreme but still want to go off road. The Dike across from the soccer fields on Wingate Road. I haven't taken the Eagle there mostly b/c I don't have my license and she's not registered or even off road worthy yet. I've ridden bikes back there a lot, even on a bike it's pretty fun.
I've only really seen the coast of New Jersey, when I was at Fort Dix. It would be hard to imagine much dirt around there to a western boy like myself. But I have heard that much of New Jersey is in the country. I wish I could have seen that part of the state… mike
