There is a different system in BC actually called Permission to Accompany, where a BC resident hunter applies for permission to accompany an out of province hunter (ie: me).
I obviously can't actively hunt our moose anymore as it is a limited entry draw which I don't believe I can participate in, so I purchase a mule deer tag every year and just hunt for mule deer. If I'm with my BC resident hunter who has the permission to accompany, he has a LEH moose tag and we see a moose, then it's his to shoot. Vice versa, if we see a mule deer than it's mine to shoot.
Pretty simple really. I know there are guys out there that are abusing the system, but if you're like me and just stick to the rules then it's a stress-free hunting trip with good times all around.
