I remember making a post about the tunnel at the Toledo Zoo being renovated and few years ago and now it seems it is finally going to happen. The creepy tunnel used to be one of my favorite parts about visiting the Toledo Zoo when I was a kid. The tunnel took you from the parking lot, under the Anthony Wayne Trail, and into the zoo. Sounds like it could be open in time for the Lights Before Christmas, but I am assuming it probably won't be as creepy as it used to be.
