Does anyone know? I asked a MN USA officer and got a rather political BS answer about safety. MN USA pays a lobbyist to supposedly work for us and with our friends in the capital. Seems like easy pikins for the DNR sitting at the end of 28 mile Lake Vermilion and many other MN lakes... MN has two snowmobile manufacturers in our state and it sure seems like MN is doing all it can to kill the sport. At least we'll have a new billion $ vikings stadium for 6 home games a year!!
