simonbp@JasonThorne Denver looks weird because they razed the entire (streetcar focused) downtown in the 70s for a few oil company skyscrapers and huge parking deserts. It's taken a very long time to heal from that vandalism.

@simonbp @JasonThorne I’m not exactly a militant urbanist, but the way we sacrificed so many downtowns to parking and highways has driven me pretty close.
