This thread has prompted me to start a running tally that I could put into a computer folder in order to printout and put into my wife's, children (when they get to that age) and certainly into my own vehicle(s). Things like using a watch (with hands) to indicate direction, using the stars for direction, and the basic information that I normally take for granted, would be shared.

Just another "preparation" project my wife would eyeball me and think, "He's paranoid!"
