I LOVE this picture...man.  Hats off to the plow operators.  I have to say that after a year of two of plowing I can relate to the hard work, the hours, the stress and the money that goes into keeping driveways, parking lots and roads clear.  It can be a thankless job and often plow operators are the first to blame when the snow piles up.  I 'd like to be the first to say thanks to all of you that do what you do.  It ain't easy and I applaud the dedication that you have!
