Making the Alaskan Highway this summer, whenever I pass a bear on the side of the road, took me 15 seconds to make U-turn and take the pictures.
Also in Alaska, as well as Canadian provinces - it is legal to stay overnight whenever you can.
Only few rest areas in prime locations had "no overnight" (thanks campground owners) , while some Rest Areas were nicer than $50 RV parks.
I did stay at state park in Alaska, with fire rings, but they had ban of campfires due to forest fires 50 miles away.
Nobody was extinguishing the forest fires, so they were going for a month.
