I’m not an urban explorer but I play one on tv. When I was a kid my parents moved us from suburban Florida to the side of a mountain in New Hampshire. Our house had once been a sugar shack that was part of a large estate and hotel complex. The hotel had closed and the estate had been broken up but there remnants of all of it in the woods. One of my favorite past times as a child was walking through the woods and following pipes. It was amazing how many different and varied sourced of water could be found on a small mountainside. Now when I am out in the woods, I look for signs like pipes or other traces of technology and follow them to their source.
