peoples choice. a little background?

People's Choice is not covered by KCBS. That is solely up to the competition organizer, so you will have to ask them how it works. I've seen everything from blind (where the food is turned in and set out in a tent identified by number) to on site (where the people come by your site to get samples). If it is on site, the winner is typically the local team since they can bring out friends and family to vote for them.
