Hello all, I am new to the sport of snowmobiling. I have been riding with friends for about two years now on the extra sleds they have. I have recently purhcased two sleds, a 2003 Polaris RMK 600 and a 2006 Polaris RMK 700. I have been having a blast but would like to learn more about the two sleds. If anyone can point me in the right direction as far as the best web sites I would appreciate it.
