I was told that all Michigan trails would have been shut down in the sixties, if not for a group of cycle riders getting together and forming the Michigan Cycle Conservation Club. They have lobbied succesfully and were granted permission to make and maintain a trail system. They have expanded the trails and connected many of them. The trails used to be groomed by volunteers, but I believe they now are groomed by the state using the money from the ORV permits that we buy. I didnt realize how good things are here, until you told me that Connecticut has no legal trails to ride. We have the Silver Lake Dune area and the Mounds orv area, they are large open riding areas.
I really hope that you are able to locate some local riding trails. Did you ask at motorcycle shops? Did you check to see if there are any riding clubs in your area?
Good Luck with your search.
