+1 more for Hatfield McCoy trail system.
I've been there three times in the last five years, and the people welcome you with open arms. Cost is $35/wk to ride 500+ miles of trails. How can you beat that? Paragon Adventure Park in Hazelton PA is $25 a day!
I grew up riding dirtbikes on the Meadowlands area of North Jersey near Giants' Stadium. I remember the days when the cops would show up just to watch us ride. They'd hang out with us for a bit, get a call and be gone for the rest of the day. Never a problem up until about 15 years ago when the enviro-nazis took over NJ. Nowadays the closet "legal" riding area is at least 2 hra south and sucks big time. At least 2 hrs west to Paragon and you've got a real nice place to ride.
NJ IS, in fact, currently working on a plan to open two more legal riding areas in the state. Finally the off road voice is being heard, and we just might get what we wanted after all.
BTW.....my weekend "SOO not legal" place to ride is only 45 mins north. Haven't seen a cop in 6 years. I think they call that Russian Roulette.
Truthfully, the cops know we ride there, and as long as we follow the trails we never have a problem. I'm sure it will all change soon enough though.
