KT,
Tell him to leave them at home. Canada's really don't like to be in with Snow geese. I have seen a large flock of Canada geese in a field many times when the snows start to come in ...and the canada's start to leave. This happens all the time here on the Eastern Shore. They really don't like to be around the very aggressive snow's and will almost always leave when the snow geese come. Snow's will however come to a canada rig quite readily. I've shot about as many snow geese out of a canada rig as I have just hunting snows with a big rig. BTW tell him to get snow's to work he'll need at least 2000 decoys. Not a joke either. Unless the sky carp have been in a field for a while it is almost impossible to entice them in without that many decoys...and that is minimal. I know a few guides that use 5000 to get a few white birds. Hateful birds to say the least. In the mid west I have heard that the geese intermingle but the white ones are the prevalent bird there anyway. Canada's have to deal with 'em. I do understand a fixtion on white geese. I hate them too.
