Terminally cool is how I would describe Denver. Every city seems to have a neighborhood that's either up-and-coming or an established area of trendy shops, restaurants and re-purposed residential space. Denver has the most of these things of any U.S. city I've visited. The people are friendly, the weather (typically) always sunny, and the Rocky Mountains serve as an amazing backdrop to the skyline (as well as a source for bookoo skiing and outdoor adventuring.) I visited for six days and had only begun to scratch the city's surface when I realized it was time to leave.
