OFSC trails? I was toying around with the idea of buying snowmobiles again, and was looking at some OFSC maps... There are feeder trails close to Kitchener-Waterloo. So, if I kept the machines at home, how long would it take to ride to Muskoka - specifically, Gravenhurst (actually Sparrow Lake - near marker 15 on the OFSC map), from Waterloo (B204) at Hwy7?
