It's important to keep the camsite scrupulously clean. The last place I took the whole fam damily to was Glacier National Park. I was worrried about bears so we didn't take our pop up camper with its soft sides, but stayed in camping cabins. But guess where the cabins were located..in the middle of a blueberry patch! Luckily we didnt see bears at the campground or on our short hikes. We made A LOT of noise! We did however see bears partying down with food in the blueberry bushes elsewhere, and every time we got in the car to go somewhere we saw them. They were fattening up for hibernation. This was in mid August.
