Elkrun,
I agree the difference is that I usaully spend the night. I still think you could do it for the day as long as you went through Customs going and coming. The Canpass does work great. You can make the call on your cell phone to clear customs. I've always had success with it. I don't think you will ever see the law changed to allow us to fish kings like they allow halibut. There's still too much friction between the Canadians and American regarding Salmon allocations. I fish there a lot in the summer and although they like our money, I frequently hear remarks about the Americans getting all their fish. Especially in reference to the Alaskan Commercial fishery. You are within a short run of some darn nice king fishing. Good luck with your pursuits.
