Question: How do photographers obtain legal access to places that are "off-limits" to general public. I am going back home in October and I would like to visit Centralia, Pa. Its a old town that has been abandoned because of an underground mine fire. Do you contact the police department / city hall (of the bordering town?) and ask for permission? I assume they would want you to have insurance to cover you if you get hurt, maybe even sign a wavier? I'm just looking for the proper professional way to do what i would like to do. Any insight would be greatly appreciated.
