A bear-viewing lodge hands you more than most: at Knight Inlet the rain jacket, the rain trousers, the wellingtons, the binoculars and the life jacket are all theirs, and they are good. What is left to buy is layers, scent-free everything, a soft bag under the floatplane weight, and the camera. The camera is where the money is, and it is also the one thing nobody will lend you.

These are the prices behind the Knight Inlet packing list, added up two ways: the clothes and the small things that every guest needs, and the whole list with the long lens in it. I have priced what I actually carried, at street prices, and the list is the one I packed from in the autumn.
