God, don't drive drunk in Boulder. The cops have nothing better to do than look for drunk drivers. They live for it. That and busting college parties, which often goes hand-in-hand with catching drunk drivers.
DD FTW.
I have a friend who made an illegal turn in Boulder, cop pulled her over, and she got a DWAI (Driving While Ability Impaired - you have alcohol in your system, but less than the 0.08 DUI minimum). She was underage at the time, and got royally screwed.
