I had a friend who worked at EWEB.  He said all of the linesmen were extremely careful to brake for squirrels.

The squirrels were responsible for many of the outages that got the linesmen time-and-half and overtime restoring power.  

Every live squirrel they didn't run over could mean hundreds of dollars when it took out a line!  

"Run safely little squirrel!  See you later!  I need a new propeller for my boat!"
