A group of us are looking for some old run down buildings, sweet graffiti, etc.    
Been searching on google for a while and haven't came up with too much.    
I did find that nelsonville has a water treatment plant that's run down. But I read it's been torn down.

I did not know the big "grain elevator" off 70 and Hamilton was abandoned. If the ladder would hold me I would climb to the top. Would make sweet shots.
