Well i know that in the majority of Alberta hunter orange isnt mandatory because there is such a low number of hunter per square mile during the season so it isnt mandatory and also lots of the land is private.In the areas where most of the land is public hunter orange is mandatory for the simple fact there are alot of hunters on public land and well it stops you from getting shot.But i hunt on private land so i dont see the need to use hunter orange because i know where everyone is but on the odd occasion when someone else is in there hunting i do wear hunter orange because i dont want to have my life rely on the judgment of someone i dont know. When i am out hunting with people i do know the only time i use orange is when we are pushing bush or i have shot and animal and im draggin it out because i have heard of people caring animals on their shoulders then getting shot at so i make sure i wrap the animals in anything bright and noticable i have when im transporting an animals out of the bush. Hope this helps you a bit and good luck on the speeches.
