I am less concerned about bears in the North than in the Lower 48.
Why? Because they are still hunted and fear humans.
I've biked a up to Alaska and the Yukon a half dozen times.
Remote camped by myself. I always light a couple of smudge fires.
Not only do they keep the mosquitoes down, but they announce my presence to bears.
And I am am rigorous about how I prepare and store food.
It is the first thing I consider when picking out a campsite.
