There’s plenty of public art in Denver, including a blue bear and this horse in a red chair (here and here, respectively). Tourists can also sneak a peak inside the Unsinkable Molly Brown’s house on Pennsylvania St.
What I didn’t get to explore, however, includes Tesla’s time in Colorado Springs, the Forney Transportation Museum, NORAD, the remains of the Jewish Consumptives’ Relief Society (apparently still findable behind a mall somewhere), and Gary Sweeney’s “America: Why I Love Her” map at the airport.
