New phenom: Urban Exploration (UE)
Just got this passed along to me by my man Sasseriansection - this looks like some *crazy.ass.shit* that Rob and Getchell would most definitely be into. I don't know how to explain it other than, these guys spelunk through places they're not supposed to be. Whether it be 300 year old abandoned victorian mansions with underwater ballrooms, abandoned half-constructed nuclear reactors, a San Diego jail, an abandoned aircraft carrier, old insane asylums in New England - you name it, they explore it.
Looks like tons of fun. Seriously.
Here are some resources:
