I never did make it to Sioux City when I visited Iowa four years ago. So I decided to check it out on goolge maps. Here's an neighborhood just outside downtown. A little rough around the edges, but that's the kind of area I often visit when on a trip.
First an aerial of downtown
The Ponca Tribe of Nebraska
Residential
Something looks out of place
A small business section in the neighborhood

The railroad tracks in Harrisburg form a huge physical barrier that bisects the city and cuts off the north side. There are multiple socio-economic factors at play here, but I've wondered how things would have looked if the tracks were never there.
