Well first off Lars,
As for my friends to the north of me, they have countrymen to their East in Quebec CA, I do not think that they would take it too kindly that you want to hunt their countrymen. (Canadiens)
So what I think you are after are Canada Goose decoys, right? Try praiewinddecoys.com I think Jim carries oversized/mag Canada goose wind socks there. If he does not-then I do not think anybody carries them. Northwind used
to make super mags size--but they were too big and not made anymore from ,my understanding.
