QUOTE : The hikers are all starting to look the same to me -- fit white dudes in safari wear, powering over the passes faster than I will ever be able to. One of these hikers is wearing a sort of sweat-soaked towel around his neck, and presently he stands above the trough and wrings out the towel into the water.<br /><br />Today the spring is running, and a little water trickles from the pipe into the trough. But the spring is not always running, and hikers after us will have to filter directly from the stone trough. <br /><br />No bueno, I think.<br /><br />Another man, dressed nearly identically, appears and dips his sweaty shirt into the trough.<br /><br />No bueno, I think again.
