What doesn’t the Mile High City have? There's a thriving cultural scene, with its famed Denver Art Museum and giant Denver Performing Arts Center, a bustling singles scene, and the Wall Street Journal ranked it 16th in cities with "high relationship formation rate"—meaning that all those singles are actually dating. Then there’s the bus and light rail, making it a transit-happy metropolis, and the nearby Rocky Mountains for winter skiing and summer hikes up 14,000-foot peaks. Oh, Denver also has legal pot, supported by 65 percent of Millennials.
