Found a nice quote on another lost urbex site. The direct link is hijacked by the Webring code. I found the site thanks to the Wayback Machine.
“It’s not about busting into businesses and bragging about trespassing. It’s about living a time that is rapidly disappearing, sinking under a new city. The undoctored past is a rare thing to have the privilege to experience, especially because this is not the past of kings or generals or millionaire mansions. This is the past of sewer and drain workers, factory workers, builders, tunnelers – ordinary people who built the labyrinthine hive of humans, that maze of rooms and halls above ground and under that we know as – a city.”
