I know this is definitely not a lot of people's cup of tea (beer) but Pabst Blue Ribbon is quickly becoming a guilty pleasure of mine. Down here in Southeast NC, it is definitely the cheap beer of choice. Every bar in Wilmington sells PBR $1-$2.50 depending on where you go. I'm talking the Tall Boys too and Jesus, you pound a few of those and you're off to the races.
Has to be in a can too. It adds to the white trashiness of it all.
