In addition to pornography, steampunk, taxidermy and science, I also have a semi-obsessive interest in urban spelunking and "secrets of the built environment." And though my interest is great, my knowledge is usually very general or generally lacking (at least in expertise).
I'm not a pornographer (yet), I haven't built anything steampunk (yet), I haven't stuffed a beloved dead pet (yet), and only once have I broken into an abandoned home turned Crack Den to investigate the mysteries within. I haven't ventured into an abandoned hotel in Detroit (yet); I haven't even watched that Underworld show in the History Channel...(yet).
In other words, I haven't done a very good job at turning my interests into actual hobbies. Instead, I live a very exciting imaginary life and read BoingBoing.net as often as I'm able.
Niagra Falls has a dirty little secret.
Ooh-lah-lah, how I love urban unmentionables: secret tunnels, rediscovered underground cities, the Mole people, etc.
Vanishing Point is a nice place to visit these treasures for those who, like me, are in process of bolstering their adventurous spirit.
