I was born in Wyo and used to hunt wilderness when I was a young-dumb teenager! Not that I'm 30 years older and brighter and moved out of state I can't big game hunt the same area without a guide! I believe you can actually bird or small game hunt in Wyo wilderness without a guide and it is just big game hunting that requires a guide. If you know a resident and can talk him into getting a guides license he can take you but must be in the vicinity while you are hunting.
It is truely one of the dumbest laws in the US! I've spoken to the WG&F personally about this reg and they put their arms up in the air and smerk! Obviously Wyo residents aren't complaining because it keeps that many more hunters out of wilderness. The law was manufactured by Wyo outfitters so you know they are tickled to death with the law.
This is fairly similar to the guide requirement in Alaska. Guides are required by nonres to hunt dall sheep, grizz, brownbear, and mtn goats but no guide is required for moose, bou, black bear, bison, muskox, etc.
If you want to talk about discrimination...sick'um USO!!!! I don't think either of these regs really affects how much $ USO makes so I have an idea they will never take these matters to court?
