Colt Andrews Tunnels Bristol, RI

[ericax1208]

Hey!
I was just curious if anyone knows anything about the tunnels under Colt Andrews School in Bristol? There's almost no information on it, and according to locals, no one has been able to go all the way through the tunnels in years. They say that they don't even know where they lead. Most people think that they were used for the slave trading in Bristol that was run mainly by the DeWolf and Colt families, but I'm very curious to find out more information.
Thank you!
