You know that drunk driving kills. Occassionally, however, a dose of graphic detail serves as a good reminder. This time, a drunk driver heading into the mountains near Red Rocks killed a grandmother, and left another in the hospital for a long time.
Have a designated driver who really doesn't drink. Take your friend's keys. Do what I have done once, and rudely stay overnight without warning at the party you promised to drive home from, because you are too drunk to drive safely home. Call a cab, it is a lot cheaper than a DUI ticket. Remember that the legal limit is 0.08 BAC, not 0.10 BAC as it was a few years ago. If you don't know how many drinks it takes for someone of your weight to get to 0.08, you shouldn't be driving. For most women, anything more than two drinks is too much. For most men, anything more than four drinks is too much. If you are small, generally speaking, that means one drink for women and two or three for men. Coffee plus booze does not equal safe to drive.
Have a happy, but safe, holiday.
