Very interesting. I grew up in a very old house (built circa 1815), in a historic district in Connecticut, and am very fond of the old, the dilapidated, etc. I was very lucky in that even as a child, I felt so at home among old dwellings and historical buildings of all kinds and consider myself to be very fortunate to have lived in such a place at such a time. I was also very fortunate to work in one of the oldest psychiatric facilities in the US (The Institute of Living) for many years, founded just after the civil war, and a place known for having many interesting visitors, including Charles Dickens, among others. On those grounds, there are many very old buildings which are connected by a tunnel system that used to be used to transport people from building to building privately. These tunnels have since been closed off but I used to go down and explore them when I used to work 2nd or 3rd shift many moons ago. I will try and find some pics I took of these very creepy places and post them in the future. Thanks
