I can't believe you went to the roof! We could only get into 2 buildings and one was a break room for employees and the other was one of the warehouses. The door was cracked. We went to every building and could only find the one open. It was incredible- most definitely one of my favorite places to visit. I have more pictures on my website nickexplores.com
