Oh yeah, and the reason that Downtown Denver is crooked, literally, I'm not talking about the politics this time, is because the trappers started setting up buildings where the Platte River and Cherry Creek met. You build one building, then build all the rest of the buildings square with that first building. After they started getting past Broadway, they decided that Denver was going to be a "real" town and starting building everything on a north/south grid like every other town.

I also recently watched about half of a 2 hour program about how the states got their shapes. That was on History I think and was pretty interesting. I'd check it out if it comes back on again.
