Dorothy needs to stop littering

I went for a run today.  I google-mapped the route but didn't look at the satellite images or anything.  So I'm jogging down the highway when I see my turn, which is down a dirt road.  O.K., no problem.  Well maybe one.  There aren't any road signs on dirt roads.  What they do have is plenty of Busch Light cans on the side of the road.
