Urbex is something I've always been interested in but barely done any of. I've explored a few places with large gaps of time between. Between the worry associated with things you've mentioned as well as lack of knowledge of locations in the area it's always just been something I never really got around to making an effort to do.
That said... maybe now is the time to make that effort and do some research and planning. I'm looking for ways to change up and make my photography more interesting. Perhaps this could be it.
Thanks.
