On a crisp fall day as the scent of burning firewood tickles one’s nose, a flock of Canada geese flies through the dusk sky, the birds’ trademark honks punctuating the breeze. This could be an encouraging image, because the best part about Canada geese is when they leave.

Golfers know this better than anybody, since these fowl absolutely love using the links as their restroom. (Especially municipal courses with little incentive or few resources to scare these the flying bags of dung away.) A few days of geese on the golf course can ruin its playability, not to mention one’s clubs, balls, shoes, and clothing.
