Finally, Midwestern waterfowlers who aren't content to stow their gear quite yet can worry snow geese. March is usually the start of the annual spring migration. The most successful goose hunters scout relentlessly for active feeding fields, set vast decoy spreads and use electronic callers (where legal) to entice these prolific birds. On a Nebraska hunt a few years ago, two hunters from our group "cow-boarded" them. Hiding behind a large plywood silhouette of a cow, these guys snuck up on geese feeding in a field.
