Welcome to the board Ram! As you can see, locations in Massachusetts are fairly scarce. Most publicly accessible trails are in fact out west, past Worcester.
The advice given to join a club is probably the best way to gain access to numerous trails. That includes many private land holdings that clubs or the NEA may have access to. Without knowing your exact location, a few clubs I can suggest in the MA area are: New England 4 Wheelers, Freedom TrailRiders, and Jonfund. All three of them are non-make specific. There are others but they're Jeep only club. (Check out the
Member Club listing for some of their websites)
Of course all these clubs are great choices, and we're always looking for more people dedicated to responsible land use, land access rights, and helping find more land we can access (Public or Private). So settle in, get comfy, and hope to see you on a trail soon.
