Re if they find nothing, they will not come back:  In Yosemite, where campers outside the developed campgrounds are required to use bear boxes and advised to sleep 100 yards from their storage and cooking site, they are also told to leave the bear box in plain site.  The bears have learned that if the box is there, it means that they can't get food.  Here I am talking about the portable boxes that we carry when backpacking.  I have not camped in Yosemite, nor even near there in many years, but I reviewed the regulations last year when I was considering it.  Chose another trip for other reasons.  In Yellowstone, however, we were told that even if we carry a box, we must hang the box.  Same in Glacier, though at some locations in Glacier, there was nothing to hang it from.
