recycled frogs?

Mark Twain's writing career sprang into life with a tale overheard in a bar, which he captured on paper and sold as his first short story. The story behind the tale has lead to an annual frog jumping contest, first held in 1928. Frogtown is home to the 39th District Agricultural Association and the Calaveras County Fair & Jumping Frog Jubilee. The very first year, 15,000 people showed up. Thousands still attend.

What happens when the contest ends? Or, as the Napa News asks, "What to do with 2,000 slightly used frogs?"
