Notice....how stupid

This is the sign in our local grocery store parking lot. It has been in place for several years now (at least 4), but it always makes me laugh when I pull in. I know they put the rocks there to keep people from running over the median (like people will do to save 6 inches of driving....but really. I would like to know how many people actually hit the rocks (which are about 2 feet tall) before they had to put a sign up to show there are some really big rocks on the ground.

But it makes me smile.
