re: Any OBers have an experience with quicksand?

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.
