This was an awesome show we caught tonight on The History Channel. The city they featured tonight was Chicago. Some of the things they went over we already knew (like they split the first atom under a football field here). However, we learned about an underground railroad that use to deliver goods to the department stores in the 20's. They even showed us how that tunnel was built. Now, since I am not from here originally, it makes sense I did not know a lot of things they showed us. However, Bill has lived here all his life, and he learned a ton of new information too! We are Discovery Channel freaks, but I think we have found another channel we are going to start watching regularly.
They check out different cities each week that have a world underneath the streets. I highly recommend setting up your Tivo to tape!
