It's illegal. I went out there with permission/friend once. Super cool and whatnot. Kind of gross to.
I was waiting for it to go all Walking Dead on me.
Really sketchy. Like, hide bodies kind of sketchy.
I'd make the trip. Sounds really cool to check out.
Having a cop say it's ok is not having permission, unless he's authorized by the owner/responsible party. I have cop friends too, that would join me on the trip, but I'd rather have legit permission
