Lebowski Fest ’08 is being held in Chicago!
 
Unlimited bowling, White Russians, Creedence cover band, screening of the movie, what have you.

What more could you want?

The most amazing thing to me is some of the costumes from past events.  There is no character from the movie too obscure that someone hasn’t dressed as them.  Also check out some of the past events such as tossing out the ringer full of dirty undies or throwing a coffee mug at the Dude’s head!
