Ok we've all been in the situation where your suck in the mud on the open tundra and not a tree in sight. Usually you have a buddy along and winch to his wheeler. But what if you can't. What do you use to winch to? I've heard of some people using a kind of boat anchor-like setup that just digs deeper into ground the harder you pull. And it comes right out of the ground when you yank it the other way. Has anyone here used them if so how well do they work and where might I get a simliar item.
