    I am not familiar with how to tell difference between an indoor city and an outdoor city.

    Source(s): I used to walk between basements of many downtown buildings in Houston decades ago. The same thing is possible in St Paul when going between 2nd floors by enclosed elevated walkways. But in both those cases, that is a tiny fraction of a whole city housing millions.
