I hate the BC government for doing this. Im sure you can imagine the problems it will cause for Security personelle and the RCMP. The # of drunken drivers will probably rise, as more people can stay out later drinking, more people can get off work and run to the bar and stay till 4am! Its a really dumb idea, and I support MADD wholely in this case with their stance.
From another point of view, I GUESS some might consider it nice to have the bars open later, but really who wants to walk out of a bar only to see the sun coming up? (well this isnt the case now, but it will be).
