I'm adamantly against shit like this. Who is this going to stop? I know plenty of people who would either find an unscrupulous bar at midnight, have a friend come over with a handle, or wait until the bars opened again the next night (still their birthday) and get even drunker, because they'll have more time to drink.
This is the dumbest legislation ever. I hope they riot in Minnesota when they hear this. Although, I am sure they'll all just take it like pussies and wait till the next night.
My generation never bothers to stand up for itself.
