I'll be visiting Colorado (from NYC) at the end of July - from 7/24-7/29 to be exact. While I probably won't be out at any events - I get Tiesto the weekend before in NYC right before Red Rocks and I'm not into DJ Dan, does anyone have general recommendations about the area? I've never been before and am figuring out where to stay - Denver or Boulder? That, plus any other good recos on places to check out (or avoid) would be appreciated.
