yesterday, we rode 81 south out of sherman station. it appeared to be freshly groomed and the riding was awesome. however, after about 20-30 miles the trail just seemed to dead end at a logging operation. we rode up and down the road in all directions for over an hour but found no trail. we also talked to 2 guys who were plowing the logging road and they said they knew nothing about any snowmobile trail. anyone know whats up whith the apparrent closed trail??? we saw nothing posted closed and the trail appeared groomed within a day or so of us being there.
