The Chicago Sewers: My Secret Base - Satan's Secret Sewer (Gallery 25)

Of over 300,000 manholes in Chicago, this location paramounts to the greatest sewer location. This is a nice central location, the birthplace of Chicago sewers, the headquarters of the Chicago sewer system (it is 8.5 blocks away from the 1977 center point of Chicago).
