"My particular dread--the vivid possibility that left me staring at tree shadows on the bedroom ceiling night after night--was having to lie in a small tent, alone in an inky wilderness, listening to a foraging bear outside and wondering what its intentions were. I was especially riveted by an amateur photograph in Herrero's book, taken late at night by a camper with a flash at a campground out West. The photograph caught four black bears as they puzzled over a suspended food bag. The bears were clearly startled but not remotely alarmed by the flash. It was not the size or demeanor of the bears that troubled me--they looked almost comically nonaggressive, like four guys who had gotten a Frisbee caught up a tree--but their numbers. Up to that moment it had not occurred to me that bears might prowl in parties. What on earth would I do if four bears came into my camp? Why, I would die, of course. Literally shit myself lifeless. I would blow my sphincter out my backside like one of those unrolling paper streamers you get at children's parties--I daresay it would even give a merry toot--and bleed to a messy death in my sleeping bag."
