If you’re looking for a quick getaway from Denver with one-of-a-kind experiences this winter, put Tucson on the list. A short two-hour flight to Arizona’s second-largest city brings visitors to a unique patch of the American Southwest, with history, food and sites that can only be seen and tasted here. When I headed to Tucson for a winter weekend of milder temperatures in January, my expectation was to have Southwestern experiences similar to those I’ve had when in New Mexico or southern Colorado or even Phoenix.
