As a long-time outfitter in the barrenlands, I can vouch for the fact that griz will learn to come to shots. After 25 years of leaving gut piles, it's become obvious that "resident" bears will pick up on the fact that a shot means a gut pile. The problem arises when they get too confident (usually the younger ones), come right away and try for the whole animal. 2 years ago I was forced twice to leave full carcasses or shoot and go through the paperwork.

Bears are not dumb. Our main camp, on the lakeshore, is on their hunting trail, ............but as soon as we show up, they adapt and make a big detour, avoiding the camp, meat smells or not. Most are no problem and they've leant to leave us alone and they won't be bothered, but it's obvious they've learnt to deal with us over the years.

All of this "education" has been learnt or acquired on their part, as we're 200 miles from any civilization and 75 miles from any other hint of a camp.
