Thanks for all of the replies. This is being hosted by the local Men's club in some hall. Unfortunately I don't think they allow smoking; yet that won't stop me from bring a few stogies in the event there is room & time for a post "feed" smoke. Booze is covered as this is an open bar event.
Like Bob said: As much as crab & alcohol as I can stuff in me. Should be a good time. I'll try to snap some pics with the iPhone to document the destruction.
