I am also planning on bringing one....whichever is my best beer (IMO) avaliable at the time....no, I am not brewing special for it. That makes it far more interesting. Ninkaski (or whatever it is) is a bad idea now that this hobby is popular.
Bring your best, expect to win, and if you don't, you get important feedback to try again next year. Too many entries dilutes the ability of even good judges (of whatever rank) to provide good feedback.
