gettinbasted, you might want to check out the IBCA rules at
http://www.ibcabbq.org - it's not heavy reading, there are only 15. Turn-in times are usually an hour apart, but it all depends upon the size of the contest. In general, contests either don't post the turn-in times or provide the disclaimer that they are subject to change depending on the number of teams in the contest - you'll find out more at the cooks meeting or from your head judge. I can't speak for exactly how they do things in the AR Pit, but you might want to contact the organizer or look at the .pdf for info about the contest - the .pdf is at
