This is the press release for his video collection on Youtube;
"I bought a house in a town I found off the internet for it's cheapness. Got a 3 bedroom with huge yard for 28k. Five years later a huge storm caused me to find out I have a significant sized 80 year old tunnel under my yard. I creep and crawl around the neighborhood and also do as much library research as I can about it. Almost every vid I put up has SOMETHING to do with the tunnel or it's support systems (dams/pumps/wells). I am also a natural wierdo, so it all works out well."
