"Q: What the hell is this site about? This is a site about urban exploration in the Ozarks." Abandoned water slides, underground tunnels, abandoned buildings and half-demolished malls throughout Missouri were all once fair game for this blog, and remain fair game for those who post in Underground Ozarks' forums.

Illicit Ohio has a wide range of photos and essays of abandoned places in Ohio, from the Cincinnati subway system (yes, there really is was one, and it's been discussed here before), to various and sundry prisons, government installations, hotels, hosiptals, houses and more. And don't miss the old vs. new galleries, either.

Action Squad – Urban Adventurers

"In a nutshell, Action Squad explores. This generally occurs late at night, to aid in avoiding other people, particularly those with badges and funny blue uniforms. We climb buildings, sneak into factories, crawl through all kinds of tunnels, spelunk old brewery caves, poke around abandoned buildings, and run across the rooftops."

Missions of the Action Squad are fully documented with descriptions, photographs (historical & intraoperative) and sometimes maps but always with a sense of wonder at the urban flotsam they enjoy exploring.
This is my particular favourite but poke around, there's a fair bit in this gem of a site worth exploring from the armchair. [via]

Explore the abandoned - all things we build must pass into an inevitable and steady deterioration. Thanks to those who chronicle civilization's entropy and put it on the web, because it's mad fun to watch.
