The Canadian Goose is a mean, ill tempered, feathered beast of Doom. I learned early on that they were not to be trifled with (as has most Canadians), especially when said beastie has young chicks with them. Fortunately, hissing seems to be the universal sound for F*^# off. True story. I out hissed the goose.
Caution. More Geese stories on the way.
