If you set out to create a fictional city, what would be some of its more unique or defining characteristics?
Like Albuquerque, my fictional city would have two downtowns. The first is the original settlement, which was relegated to secondary status when a new commercial district sprang up around the railroad when it came to town.
There would be some dominant topographic feature, like the ridge slicing through New Haven or the Niagara Escarpment in Hamilton or the Isthmus in Madison. Of course there would also be water features, including lakes and a river. Perhaps there would be a waterfall, as in Spokane.
