Denver

The mile-high city (not least because marijuana is legal there), Denver has a mix of outdoor ruggedness and big-city living. It has a huge craft beer scene, excellent restaurants (including, Sushi Sasa, one of my favorite sushi restaurants in the world), a large international airport with lots of connections, and proximity to the mountains (and the Republic of Boulder). It’s clean, and the locals are incredibly friendly. There are few cities in the US I want to live in, but I love Denver enough to say that it’s one of them.
