Don't know if it is legal to take a snowmobile there or not? Probably it depends if the Jim Liberty cabin is located in the White Mountain National Forest or in a state park or in a town park.
Many WMNF trails have a sign at their trail head that says something like: Foot travel only, motorized vehicles prohibited, violators fined $500. Got to wonder about taking a snowmobile up there? Anyone know?
Whatever happened to 'Leave nothing but footprints, take nothing but photographs!'
