At the park near my house is a reservation of what was left of the old mill. I guess these stone buildings were part of it. Looked like Fred Flintstone's house a little.
On the backside, they had been graffiti by some moron or morons. On one side it says "You're on my mind." and the other says "I'm in your shadow." on it. What's the point? This means nothing. Someone will eventually have to remove it and it isn't too easy.
Another side had someone who spray painted a "green devil", and this is I don't get either.
