I know that winches have been a topic of interest in the forums. I ran across a Youtube video that I thought was really cool. For those who don't access Youtube, the idea is that using a few 8-10 foot 3" diameter branches or logs and a rope, you can fashion a winch to pull your vehicle out of the mud or sand or whatever.
Basically, you tie the rope to the logs in such a way that when you put the logs at a right angle to each other, end to end, and flip them over each other incrementally, you wind the rope connected to the vehicle and anchor point around one of the logs.
Of course, a difficulty is that you may not have logs available, and an anchor point may not be readily accessible, but still ... worth knowing. Might be handy to know in a pinch.
