A look back at the ups and downs during Mark Peterson's quest of completing the World Turkey Slam. Mark didn't set a goal of completing the Slam he wanted to achieve it in a single turkey season, and he did.

The subspecies, not in any particular order, are Eastern, Rio, Merriam's, Osceola, Goulds, and Ocellated.
