A head-scratcher...

I drive by a billboard the size of a Buick every day that says, "Stay ten feet away.  Stay safe.  Stay alive."  Stay away from what?  The edge of a cliff?  A cranky honey badger?  A narcoleptic hillbilly with a chainsaw?  In the bottom corner of the sign is the name of the local power company.  OK.  So...what?  Stay ten feet away from downed power lines?  From the telephone during a thunderstorm?  From a trigger-happy cop with a Taser?  If staying ten feet away from something will keep people alive, why the hell would you advertise on a massive billboard and then be vague about it?
