Winch Trick
Here's a little winch trick/tip if you ever wind up pinned against a tree.
The other day Cindy and I were out when I got pinned against a tree and Cindy asked me "how are you getting out of this one?, are ya going to winch sideways?? "Nope, I got a little trick, watch this" I responded...She was quite impressed, came home and made a video of the trick to show her friends.
Oh and to answer the question, No, you do not need to be locked in the front.
Happy trails!
