Humboldt Park Chicago by Jeff. (super loud - turn your sound down)

This is footage from a radio-controlled helicopter. It gets up pretty high and does a couple of nice 360’s, so you can see the entire city.

This old parking garage ramp feels like a time machine to the past. Descending the ramp you feel like you are going back in time, at least until you emerge into the modern city.
