We used to go to Lake Tahoe every summer, and there are signs everywhere warning of falling rock...my mother convinced my older sister that 'Watch for Falling Rock' was a sign put up by an Indian Chief years ago, becuase he lost his son, Falling Rock, and they never found him. I believe my sister was well into her teens before she figured it out....
