For years, before getting my 570, I owned snowmobiles. The last 10 years or so of ownership we got less and less snow in Indiana and had to resort to heading up to Michigan to enjoy the snow. I can't even remember all the towns we road in but most were in the lower, Gaylord, Indian River, Cadillac, are few that come to mind. How many(if any) of the public snowmobile trails are open in the summer to ride ATV's on? I thought those trails would be good to take the wife and kids on, just strolling through the woods and not having to navigate rocks, hills, mud, etc. Thought it would be nice to head up one weekend and just buzz around through the tree's etc.
