this was predictable via logic: what extending last call by an hour did was push the duis forward by an hour. that is all.

that said, there's a hidden concern, here: if you extend the hours too far, you'll get drunks in rush hour.

i think 4:30 am is the right time, myself. as mentioned: not all of the bars will stay open. but, i'd rather have people drinking in public places that aren't afraid to call an ambulance than have them disperse into bushes, alleys and illegal watering holes.

4:30-5:00 is when people start looking for breakfast.
