I led a backpacking group up to Young Lakes one time. We got there in one day, and then on the layover day, groups of us spread out for dayhikes. I was up on Mount Conness, and another leader took a group up to Roosevelt Lake. When there, they ran into a fisherman who had been out on his own for too long. He had left Tioga Pass with five days worth of food. There he was fishing at Roosevelt Lake, and it was his eighth or ninth day, and he was out of food. He had a small string of caught fish, but he was getting sick of only fish. The fisherman followed that group back to our camp at Young Lakes and he asked us if we would trade some of our normal food for some of his fish. OK. We kind of felt sorry for the guy. So, that night we had a meal with trout pieces on the side. After dark, I was tidying up camp to make sure that everything was kosher before the bears made their nightly romp through. On the edge of camp, I found a large bag of fresh fish guts. That is totally unacceptable. I woke up the fisherman, gave him a small shovel, and told him to bury the fish guts out in the woods someplace. Having fish guts laying around like that would have brought in the bears from all around.
