was the first of several wetlands we'd traverse on this trip. Some natural, some man-made. I'm not a bird-watcher or anything, but it's impressive how much wildlife depends on what little water there is out in the desert. I've been thinking a lot about diet and nutrition and this whole paleo movement, and had come across this National Geographic documentary called "The Last Feast of the Crocodiles" which is totally amazing and fascinating and gruesome at the same time. <iframe width="420" height="315" src="http://www.youtube.com/embed/DuyAsq4m2I0" frameborder="0" allowfullscreen></iframe> I'm not going to recommend all four parts -- I'm just going to say that after seeing the first part, I couldn't stop watching. Where am I going with this? I guess for me, a big theme of this trip was about how the extremes of survival have really ceased to be selective pressures or evolutionary influences of modern humans. We mostly eat processed crap, we are largely sedentary, our lives are rarely if ever in any real peril... and I'm not so sure we're the better for it. What I love about what we're doing on these trips is that we're forced to think about where we're getting our food, and water, and we depend on our skills to build fires, and make shelter, and navigate, and troubleshoot, and it's very physical, and it profoundly rewards every sensory nerve ending we have, from the visual splendor we saw, to the deep ache I still feel in my shoulders and arms. THIS is living.
