Sitting in Little Yosemite Valley eating rehydrated lasagna. Left out from the backpackers' camp early this morning and made the 4.3 mile, 2000ft climb. With my pack on, it absolutely wore me out. Suppose to do Half Dome in the morning but debating. It's another 2800ft up. Of course, I don't have to do it with my pack but I do need to get me and my pack back to the main valley after the climb. Will see how I feel in the morning! Weather is perfect here!
