Thanks for the kind words -- foot is doing a little better (although we just spent another several days hiking in the Sequoias).
What's in my backpack? Let's see -- four liters of water, tripod, camera, extra batteries for camera, windbreaker, survival equipment (water filter, tools, etc.), GPS, maps, compass, and binoculars. Kind of heavy, but since we go into some remote areas, I would not feel comfortable without the survival gear. We are prepared to spend the night if necessary -- if I were to break an ankle, there is no way Felice could carry me -- I weigh almost exactly twice what she does.
