The area of Berlin, NH. But includes for summer ATV usage Berlin, Gorham, Success, Errol, Pittsburg. Winter usage is ENDLESS...you could start in the Berlin area and run West to VT or Canada, North to Canada, East to Maine, or South to just about anywhwere in NH...About 800 miles for summer riding currently and THOUSANDS of miles of winter sled trails.
I have been totally scheming on property up around this area to do something similar to D-Town...but it would be Sleds and Winter Fun too.
