In reality, the easiest way to get this done is for HIM to post instead of people just constantly posting up "He is stuck".
If he is on trail and it won't fall apart when you get a winch hooked up and can drive away under its own power, then there isn't really an issue.
But if he is off trail, the best bet is to let SRD get him out. If you get busted helping out, they don't care if you are helping out or not.
If it is in need of a tow after, Big Hill is right in Cochrane and does this kind of thing all day long. Yeah, he will pay ($160/hr from when they turnt he key in Cochrane) but that cant be avoided if that is the situation he got himself into.
