Yeah, the flip-flop winch would be a good option provided you had a tow/recovery strap and a few tools (a saw would be helpful, a shovel doubly so). I do need to get a recovery strap!

I do keep enough stuff in my car to survive at least a week in the wilderness in very cold temps; that's a week before things even got uncomfortable! Partly it's due to growing up in the midwest where huge blizzards are commonplace, and partly due to me being an avid outdoorsperson.
