I hunt in N Idaho, I swear grizzlies are like big foot, just a fairytale. Been on a multi-day backpacking trip in Glacier NP, never saw. Been in heavily g-bear area by Island Park Idaho, never seen one.
Now, even though I believe they dont exist doesnt mean im going to be sloppy or lazy. Just be wise, keep food from tents, and look into a lot of the attacks and what caused them. Most of the time its due to human error, aka startling a bear. If you get something down, gut it and try to move the meat from the carcus. If youre having to pack in and out to get the meat out, try to set it up in a way you can see it ahead of time. Or shine a light on it before going to it. Be bear aware, but dont allow them to control your hunt.
