Went back to the old Atlanta Prison Farm (with a fully-charged camera battery this time) and checked out the prison buildings, which were in operation from 1945 to 1995. The roof caught fire in 2009 and the building was left to burn since it was long since abandoned by then. The lower floors are still pretty much intact but are hard to photograph due to lack of light.
I was particularly impressed by some of the graffiti we found. It was a cloudy day so the light wasn’t ideal, and I still need a decent camera, but here’s what I have so far.
