Here is the way that I view people's choice in the heartland (Missouri, Oklahoma, Kansas and Arkansas). Most, not all, are hosting a cook-off as a part of some charity, whether it be the chamber of commerce, rotary, elks, etc. Usually the meat is donated for the PC. They hope to make money from the $5 sampler kit they sell to the public. Sometimes, the only money they raise for the charity is from those kit sales. Any of you who have ever ran a cook-off know the expense that goes in. If they make very little for the charity from the cook-off, the next committe meeting might be on the lines of: Let's ditch this and have a car wash! And cook-off for next year is no longer.
So, my advice is this and it is something that we have followed for years. Give without expectation of getting back. Most, not all, surely have room for one extra butt or brisket. It doesn't take long to season and we do nothing special to that meat. We have a large cooker and always volunteer to cook extra and usually do, but only after others have had their chance to volunteer. Oh, and we have never won a PC anywhere, even in our home town. We just want the cook-off to be successful and raise money for the charity and hope they host again next year. The only caveat that we have is they must hand out the samples.
Perhaps if you look at the people's choice situation from this perspective, you will see where you are the benefactor from just a little effort and you get to go back to that town and cook again next year.
