Abandoned buildings, mines, storm drains and tunnels have become the playground for a new generation of urban explorers.
"As economies and demographics shift away from manufacturing thousands of buildings, tunnels and drains are left empty...[the] frontier has turned inside out: Now a great wilderness lies inside what we have created, used, altered, forgotten and discovered again." Around the world, motivated by curiosity and a love of storytelling, intrepid adventurers have infiltrated this urban wilderness and documented their haunting travels. The practice has become known as urban exploration, or "the investigation of human-made structures not designed for public consumption." Recently, the large web presence of urban exploration sites has allowed the less daring to virtually experience the abandoned locations.
