Idaho CO's are great, for the most part.
Washington's almost always seemed to me to have a "you have to have some sort of infraction I can ticket you for" type attitude.
I have only bird hunted in Washington over the years, so this opinion does not apply to big game, for me.
I would assume the same folks check big game, though.
I have the same report on the fishing side of things.
Idaho guys are wonderful.
Been checked by Washington and Oregon officers that were a-holes.
P.S. I hunt & fish legally and have never had a ticket in any state.
