So, there's a man crawling through the desert.He'd decided to try his SUV in a little bit of cross-country travel, had great fun zooming over the badlands and through the sand, got lost, hit a big rock, and then he couldn't get it started again. There were no cell phone towers anywhere near, so his cell phone was useless. He had no family, his parents had died a few years before in an auto accident, and his few friends had no idea he was out here.He stayed with the car for a day or so, but his one bottle of water ran outand he was getting thirsty. He thought maybe he knew the direction back, now that he'd paid attention to the sun and thought he'd figured out which way was north, so he decided to start walking. He figured he only had to go about 30 miles or so and he'd be back to the small town he'd gotten gas in last.He thinks about walking at night to avoid the heat and sun, but based uponhow dark it actually was the night before, and given that he has no flashlight, he's afraid that he'll break a leg or step on a rattlesnake. So,he puts on some sun block, puts the rest in his pocket for reapplicationlater, brings an umbrella he'd had in the back of the SUV with him to givehim a little shade, pours the windshield wiper fluid into his water bottlein case he gets that desperate, brings his pocket knife in case he finds a cactus that looks like it might have water in it, and heads out in thedirection he thinks is right.He walks for the entire day. By the end of the day he's really thirsty. He'sbeen sweating all day, and his lips are starting to crack. He's reapplied the sunblock twice, and tried to stay under the umbrella, but he still feels sunburned. The windshield wiper fluid sloshing in the bottle in his pocket is really getting tempting now. He knows that it's mainly water and some ethanol and coloring, but he also knows that they add some kind of poison to it to keep people from drinking it. He wonders what the poison is, andwhether the poison would be worse than dying of thirst.He pushes on, trying to get to that small town before dark.By the end of the day he starts getting worried. He figures he's been walking at least 3 miles an hour, according to his watch for over 10 hours. That means that if his estimate was right that he should be close to thetown. But he doesn't recognize any of this. He had to cross a dry creek bed a mile or two back, and he doesn't remember coming through it in the SUV. He figures that maybe he got his direction off just a
