Well I 'd be lying if I said I'd never been stuck, but deliberately going off road doesn't really count. I did get stuck some years ago when taking a high seat out in a trailer to a remote part of our estate. The trailer snagged and I broke through the surface into a boggy bit. Although I had a winch, we soon ran out of things to winch to as they were all ripped out of the ground. In the end, we buried the spare wheel - a trick I had heard of but never tried. It worked a treat. We couldn't dig that far down so we did what we could and then built a cairn on top to weigh it down. We really were in deep and the ropes were as tight as I've ever had them in any situation. Gradually with the lockers in and the winch pulling through a snatch block, we got out. Of course then the challenge was going back the way we'd come!
