Warning! The salt will shrink you to a tiny proportion of yourself if you stay out on it too long or go out on it too far. Be careful! Salt leeches moisture from your body and so prolonged contact to it does something similar to drying fruit. (You know those little dried apricots are no where near the size of their plump juicy ancestors.) This is the number one reason people tell you to bring water to Death Valley, especially if you go out onto the salt flats. You have to rehydrate to prevent this kind of thing from staying permanent!
