This reminds me, a while back on Nantucket I had a Tacoma w/w. I was aired down just fine and was driving along a fairly firm and wide expanse of beach at low tide. All of a sudden WOOMPH! The drivers side of the truck sank to the axles while the pass. side was still on
solid sand. Un-be-knownst' to me the beach here transitioned into a wet muck texture not visible from the surface AND THE TIDE WAS ON ITS WAY IN!
Its always bad when you dig around the tires and immediatly find water. I had been concerned before about being stuck on the beach alone without a winching point so I carried around a 3' Danforth boat anchor. In this case I dug a shallow hole to help the anchor start to dig in and attached the winch cable. Tires slowly spinning ang the anchor pulling deeper into the sand, the truck wasn't moving.
Plan B was to attach a snatch block to the anchor with a chain and run the cable back to the truck. Well that was just what was needed and I was able to get out of the salty muck. Needless to say I had some hosing down to do including my underwear, WOW, that was an afternoon! (no alcohol involved either)
Just sharing, but the moral of the story for me is 'your eyes cannot tell the whole story'. If I were in a deuce, I think I'd still be paying the loan to the local excevator co. I still have the Danforth anchor, but I don't think its big enough now for my deuce!
Have fun but Mother Nature has some secrets!
