southtowns has lots...check out
www.mudnuts.org they're a club out of rochester, these are a few that someone told me about when i first got out to school at ub:
"ther is lots of stuff behind the summit park mall the area is called demlers.
take river road in north tonawanda make a right on liberty drive and about a 1/4 mile down you will see the beginings of a few trails there.
to get back a little further and to more interesting stuff ..
continue on river road..make a right on williams, right on Lancelot , left on Plaza. right on Jagow..go about a mile down, right after the railroad track make a quick right onto the stone road. go down the stone road for a little ways untill you come to a steep hill Liberty drive will be on the other side of the tracks to your right. turn left up the steep hill and begin 4 wheeling.
a word of caution some of the puddles on the gravel road may not look deep but be careful. some are only 6inches and some are 3 feet deep. one day I was cruising through those puddles at 45mph and hit one that was 3ft deep. luckily i didnt get that much water into the engine.
there are also some more remote 4x4 trails in the southtowns but i dont know of any specifics. jimi dean offroad should know more."
like it says call up jim dean's offroad 655-2364 they're in elma...2210 Bowen Rd
