After completing the upland slam in 2020, Mark Peterson decided to take on the challenge of completing the North American waterfowl slam... in one season; something most waterfowl hunters strive for in a lifetime. With the Canadian boarder still closed in the wake of Covid, he commits himself to pursuing this quest knowing that he must do it by only hunting in the U.S. and Mexico. With an already stacked deck, he kicks off the journey in October and heads for Cold Bay, AK to target Harlequin and gets more than he bargained for.
