Each year (we've been doing this for the past 11 years) it gets slightly less outrageous. But it is still an absolute hoot. 
Trust me, there are ABSOLUTELY no make up, high heels and dresses involved. And as little culture as possible. We do try to get in an appropriate amount of heavy drinking and practical jokes, however. One of my friends is already planning for next year (when we are all of a certain age 
). Her current suggestions include murder mystery weekends, rock concerts and theme parks... 
I could probably do w/c July 26th.
So don't go expecting anyone who's life and soul of the party - we need a Fraggle for that...
