Lots of muscle and wedge shapes: What are they judging?

Market hogs, giant pumpkins and desserts that incorporate Spam These are just a few of the things being judged at the Minnesota State Fair this year.
In addition to Midway rides and food on a stick, the Great-Minnesota-Get-Together offers hundreds of competitions.
Each day this week, All Things Considered is focusing in on one of these contests. Our series "What's Being Judged?" asks you to guess which contest we're showcasing.
