RE: Quebec Winter Caribou Hunting
Don't worry about the migration. They are still above the tree line and in fact go back and forth until it starts freezing then you will see them start to congregate into the hunting zone. They have been doing this migration for a long time now, don't worry.
As for the cops and wardens they are there to make sure people don't shoot from the road, down the road, waste game, drive a vehicle with a loaded firearm, drinking that sort of stuff. Just use your head, tag what you kill and they won't bother you.
