100% agree, I can only think of one or two public trails in pretty much all of New England, and I mean absolutely public open trails, not ones that are questionable because the land owner hasn't been contacted in 40 years..
Join a club, private land up here is the nuts. best example, last year, we were wheeling on a moderate to hard trail, minimum 35" tires, 2 lockers, and a winch. ten feet away was a bunch of stockers putting along, and on the other side there was another trail where Clayton and a bunch of KOH prep buggies were thrashing up a trail.
Join a club, if you want to PM me, I can recommend a bunch, we all basically use the same land, so pick and choose what fits you and your rig.
