@seanalyn: Ah, well thanks for letting me know seanalyn. I can understand why they'd do it that way and I definitely wouldn't want to get them in any trouble with the law. Especially on what promises to be such a joyous day of festivities!
I just got over being sick, this is my first Thursday off in about 2 months, and I live about 45 minutes away from SF. Timing couldn't be better.
I plan on going with a friend but hes only 20. I'll still be there if they're strict on the age restriction. If anyone know if they'll turn people away for not being 21 please let me know. Thanks and hopefully I'll see some of you duders out there!
