Canada goose. And I think some of that shit your grandfather showed you may have left a negative impression. On a related note, I hear geese can be trapped easily by digging a trench about goose shoulder deep, and just over goose width. With a gentle slope on one end, and bait in the trench, the geese will waddle in, and when you run up on them with a stick or hammer or whatever, they don't have enough room to spread their wings or turn around. Whack whack, goose dinner. Only to be used in an actual survival situation probably. I'm not sure that's legal at all. I might have even read that on this forum. Idk. Edited for spelling.
