Starting to plan an Alaska trip what are the boon docking

I won't go to Canada because they are so paranoid about guns. But there are gun shops near the border that will store your fire arm for a fee and you can retrieve it when you return.As to carrying in US National Parks,yes you can,BUT you cannot take your weapon into any building,even a bathroom.We were in Yellowstone last year and I left my gun in the truck when I went into a building.
