Most undeveloped land up here used to be owned by timber companies, and most were accomodating to recreational users. There were lots of old hunting and fishing camps on leased timber company land, and their logging roads and trail networks were usable by ATVs in the summer and snowmobiles in the winter. Around 2000-ish, the timber companies started closing their mills and selling off their land. Fortunately, a lot of that land has been purchased by the states and private trusts and conservancies for public use.
If developers had their way, it would all be auctioned off. But I think all the states up here have something in their constitution to prevent that. Notably, New York has a "forever wild" clause. Besides, expanding public access to land for outdoor recreation is very popular around here even among conservatives.
