Insightful information, and yeah, I incorrectly remembered :)

Another interesting thing not talked a lot about online is that these midwest cities typically have a ton of documented (or not?) underground tunnels. There used to be a cool website for the Twin Cities (Minneapolis/St. Paul) that showed them off. My parents recall walking from the University of MN to further parts downtown where you can transition to skyways and basically never go outside. I guess -40' weather really pushes people to become moles in a sense. I think a lot of big cities also have huge tunnel systems for heating fuel (coal delivery and the like) and other utilities
