One Summer day over 35 years ago, I and my father were at the shores of Mono Lake. We saw the brine flies all around and my father inadvertently fell in quick sand on one side of his body. It was so difficult for my Dad to remove his foot that he removed his socked foot from the shoe, pulled it out and then yelled: :Here is for Mono Lake as threw it several feet (16 meters or so from the shore). That's a fun memory. It wasn't Winter when we were there though.
I've been to Mono dozens and dozens of times, never had encountered quicksand! That's crazy :)
I was 13 or something but it is true. He could barley get his shoe out and when he did, it was covered with mud that smelled to high heaven.
