It was a shock to see how many were under Washington, DC, too, when I first learned of them. I think they're probably under many older historic cities, like Philadelphia. But it was also a surprise to learn they were in smaller rural towns, like the one we lived in. Agriculture was the primary business. My brother saw one of the entrances there, himself. A local pharmacist who had been there for years bought one of the older buildings downtown that still had the old trapdoor entrance. They are all over the San Francisco/Berkeley/Oakland area, as well. Up into Portland and Seattle. Men in the late 1700's-1800's were often "shanghaied" by dropping them down a trapdoor into a tunnel, where they were put on ships to serve as sailors--against their will. Looks like Liverpool was one of those infamous places, as well! https://www.amusingplanet.com/2018/04/shanghaiing-how-trickery-and-deception.html
If you ever find more info on them, please share it with us. They must still be using them. We have a shocking number of disappearances in our country. Even in the middle of our big cities, surrounded by people. People just seem to drop off the face of the earth. But I found the children disappearing from foster care in Washington DC to be especially disturbing. More children disappear from that city every year than the entire State of California where I was born and raised. And one investigator who traveled there to review the cases in DC, was shocked to find that about a third of them didn't even have a photo of the child in the police file! I am wondering now if these tunnels can be located, if people could put motion sensor cameras in them? They use them regularly up here in the forests of the PNW. Mostly by hunters or those wanting to keep an eye on their acreage.
