When I was stationed in Sinop, Turkey some of us often did spelunking in some local caves. Some passages were so narrow we had to crawl. We never thought what would happen if we came to a dead end and couldn't turn around.

Years later I did a lot of construction on a 300 year old house in the Altstadt of Heidelberg, Germany. We used torches to burn years of built up paint, sanded lots of exposed beams and bricks, pulled down old ceiling which had charcoal, hay and dung as insulation and on and on. All was done without masks or any knowledge of lead or asbestos.

My kind of friend! Adventurous. Next time, go with abnother person.That way , yopu can make a video and become famous. I love exploring abandoned places. For a few years, a while back, I researched all the TB hospitals and insane asylums in upstate New York. I visited quite a few.
keep up the adventuring.
