Any OBers have an experience with quicksand?

Not being funny but can you use it for making concrete or for sand bags?

Put my truck in a cow belly one time. Thought that thing was gone. An F250 Fx4 almost buried itself trying to get me out. But a 94 2wd Tacoma yanked my arse clean out.

I was once in a clearing in North
Claiborne Parish. Real sandy soil on a plateau-like area atop a hill. Saw some moist ground around a very small pondish area. Took one step and sunk to my knee cap. I fell backwards and managed to get out with just a boot lost. It was bad enough to scare me pretty bad. Always felt those types of areas are likely spots that feed the aquifers, but dont really know. The same trip I got hornet stung about a dozen times and stepped on a board with a nail sticking straight up... went through my tennis shoe and foot (had extra shoes in car). All that crap caused me to have sudden stomach issues.....still shake my head when I cross the little bridge I exploded under. A bad day.

Took three guys to pull me out of some in a tide pool duck hunting one morning on the bayside of Galveston. Stuck at/just above the knee and getting worse when they got back over to me

I don't believe it exists.

There is a film, dont know if its on u tube or anything about a lady getting in mud flats alaska. She sunk pretty fast, and despite people arriving and helping, she ended up drowning with the tide came back in. Sad.
