$45 for an Ontario permit looks good - until you factor in Ontario's insane insurance rates.
If a snowmobiler (or anyone else) hasn't balls enough to ask permission to be on the land then they haven't brains enough to be on the mode of transport.
The farmer was smart to be packing a shotgun. Never know who or how many you are going to run into. Perhaps the RCMP should be out doing a better job before someone gets hurt.
