I've been going for awhile too (the first time I went was in 2003) and let me just say, eat something before you go. It can be a relatively long evening and if you don't eat something before you go you will be hungry- and you can't get anything there to eat. Other than that, its really just a lot of fun, and like broadway_baby4 said the atmosphere is great, as is the entertainment during the commercial breaks.
And hang on, when did you win the discus?
