I have never been "REALLY STUCK",,,, but often think that if I did it would be at least 500 yds to the nearest tree, so a winch or come-a-long wouldn't help much.
I don't like the idea of hammering a pipe into the ground, too easy to get THAT stuck and get stuck BY that 3 months later.
I do HAVE a boat anchor (& I don't mean a nonfunctional tractor) that supposedly has 6500 lbs of holding force in a silt bottom; so I would probably hike back to the house to get that, come-a-longs, 4x4s, 2x8s, chain, garden way cart to schlep it all in and whatever "Volunteers" hadn't seen me coming and vanished before I saw them.
I like the 4x4 across in front of the rear tires and chained through the rims, or behind if backing out (usually best).
