Rub N Smoke has a good suggestion in trying to find a smaller contest for your first one to enter, or go and visit one at least before jumping in. Springfield usually has Rock N' Ribs at Bass Pro in April, but that is a fairly expensive contest to enter. Joplin always has a nice contest as well, with very decent payouts. My biggest tip to you before hand.....practice, practice, practice! The key is getting at least one brisket, one pork butt, a couple of slabs of rib and some chicken pieces done for 30 minute turn in windows, starting usually at 12 noon.
Good luck and we're here for you.....you know, we all had to start out as a newbie at a contest ourselves!
