The big brick building is no longer there. But there's still a boarded up church and two other buildings, (not sure what they are), that are still there.
When I was there, I saw no security and the only thing in the way was a chain to keep cars from driving up there. So you'll have to park at the office building right next to it and walk up. It's alright, but it would've been cooler if I had been able to get into the buildings.
