The only time I really get into trouble while hiking is when I'm alone. It was late October and a couple weeks earlier I had found a rather fun trail but didn't have the time to go as far as I liked. So I waited and watched the weather for the area and one weekend the forecast was great so I headed out, alone, right after work. I made sure to pack light, only took one camera, no tripod, left the sleeping bag and took a liner instead, small camping stove and some freeze-dried gook. Well, it was wonderful weather when I got to the trailhead and I plunged right into the hike, the plan was to push on to a clear area to camp and then take the whole next day to reach my destination and take pictures and come back the morning after. Long after dark I reached my site, set up the little solo tent, and made some truely horrible backing food - if it hadn't been as cold or the food so hot I don't think I could have eaten it. As I lay in my tent, inside the fleece liner, I began to become aware that it was quite colder than forecast. Soon out came the emergency "space blanket", that abonimable tin-foil rag. To my chagrin it didn't help at all. After hours of denying the onset of hypothermia, I finally managed to get up and pack my things. Down the trail was fast and I warmed up considerably. When I reached my car I found it encased in ice, I actually had to chip it off to open the door, ...so much for the weatherman. And that was it, drove home and had a nice hot shower and not a single picture to show for it.
