Your in the desert. the sun beats mercilously down as it does in any desert prose. A vulture circles overhead. Your thirsty. Like most urbanites you are usually in a state of dehydration falsely assuaged with coffee or carbonated soda. You have your pocket tin with a condom, folding knife and a garbage bag in your pocket. squat down in any available shade. Make a shelter from the garbage sack if needed. Loosen your clothing and let the air circulate. Calm down,think. Do the animals carry solar stills? No the animals go to the water. Watch the animals. usually they tank up at early dawn and evening, when the day and night shift are switching. Look for birds flying purposefully in one direction. Are there any wild horses or burros?This is the time to find the many 'hidden' cachements of water. Hopefully they aren't miles away. You deploy your photon 2. In the grey sublight it is adequate to avoid sheer cliffs & rattlesnakes. You leave a marker, a small cairn, rock arrow etc, to relocate your starting point and alert rescuers where you were, and are. You take a bearing with your compass. You write it down on your rite in the rain paper. In the precious cool hours you walk calmly, conserving your energy and not overheating. With luck and practiced observation, The burros lead you to a large sandstone basin with liquid gold.You filter out a few bugs with the page promoting solar stills.If Im there, I have minimum a 5 qt. Mil-spec canteen. I saved 1.5lbs on that huge bowie I outgrew and traded it for more water capacity LOL<br><br>
