The Chicago Tribune and the owner of Shake, Rattle, and Read just did a guided tour of the spooky tunnels beneath his bookstore and the legendary Green Mill.I live for stuff like this, and thankfully there is some nice perky jazz music playing in the background of the entire video, so you don’t get too freaked out!It’s especially worth watching until the end because after the tour, there is an interactive Flash map of the basement. I only wish they made clear where the “tunnel I’m afraid to go down” is in relation to the map!(via Gapers Block)
