It's also interesting to see the layouts of the capitol buildings, how they're integrated into the city plan. Some cities, like
Salem,
Springfield, or
Columbus just have elongated city blocks, some more awkward than others.
Harrisburg has a very irregular block, but that's mainly because the streets change with the river.
Boston's is across from a park,
Austin's has windy streets going into the park it's in, but I particularly like
Montpellier's, because it goes straight into the mountain. And then there's of course
Madison's, probably the best. Let me know if I haven't mentioned any good ones.
