You have to watch out for punny people and their quicksand wordplay. They will try to pull you in.
(I think it's affecting me. Someone throw me a vine before I disappear!)
Going back to Thomas' original point. I remember being a kid, and feeling like everyone had a 72% chance of being stuck in quicksand at least once in their life.
Quicksand was a constant plot device in movies and tv. In The Princess Bride it was found in the Fire Swamp, and they called it Lightening Sand. There was desert quicksand in Lawrence of Arabia. In The NeverEnding Story quicksand was found in the Swamp of Sadness. Even K.I.T.T. wasn't immune to the quicksand danger.
Last night we were watching old episodes of Nancy Drew from the 1970's. Nancy and George were walking through the woods, looking for a car that disappeared, and George suggested with a fearful voice, "Maybe there is quicksand down there, and it sunk."
I remember many heroes who only survived because of a strong tree limb or a well-placed vine hanging down exactly where they could reach it before the quicksand swallowed them completely.
Kids on the playground offered advice like, "When you get stuck in quicksand, don't struggle too much. Make small movements. The more you move, the faster the quicksand will swallow you."
We all nodded our heads gravely, and reminded each other that vines couldn't always be trusted. We were sure that it couldn't be too many more years before the quicksand caught us, but it never did. At least, it never caught me. I can't vouch for the safety of my entire elementary school class. It could be that I am just part of the lucky 18% of people whom quicksand has not tried to swallow.
Did you have quicksand concerns when you were a kid?
If you aren't curled up in a ball, trying to pretend that quicksand doesn't exist, you could check out the time I narrowly escaped being killed by quicksand just to get a picture for you.
