    Jim van Zandt advised us-
    
    | You don't even need the local time - just a stick and a piece of level
    | ground.  Poke a stick in the ground and mark where the end of its
    | shadow falls.  Wait.  The shadow will move directly east.

    Comment from George-
    
    Can't be true, though, can it?
    
    Just take an exreme case. Put yourself North of the Arctic Circle, in
    Summer, where the Sun never sets. The Sun moves right around your horizon,
    and the tip of the stick's shadow moves through all azimuths, in the course
    of the day.
    
    So, it isn't a general rule. I hope Jim doesn't rely on it in his travels,
    even in temperate latitudes.
    
    George.
