It was a close call this year. The contest is maximum of 30 minutes. They let the cow out in an area that has been carefully measured into grids. A few judges stand around the outside and make sure that the cow stays inside the grid.
After a time when it looked like the cow wasn't going to poop, they let out a second cow. The next step was to give the cows some feed. That didn't work either.
Suspense was building and right at 9:30 one of the cows "dropped" and the crowd cheered because the cow pooped. I heard someone say something about the oddity of grown people standing around waiting for a cow to poop for entertainment. (Sonya thought it was interesting to watch too.)
The spot that receives the largest amount of poop wins $1,000 then there are 10 more drawings of $100 each. Money is a motivator.
