I remember as a young man I spent a considerable amount of time hiking, backpacking, and camping in the mountains, usually by myself. Getting away from it all and honing my skills of self-reliance at the same time has always appealed to me. Maybe it is something, on a primal level, relating back to my cave man ancestry.
Senses Go Into Overdrive
It has been my experience that anytime you are completely alone that your awareness and senses go into overdrive, bombarding you with all sorts of new stimuli. At times, this can become overwhelming, and I would be lying if I stated that I have never had the hair on the back of my neck stand up when I was deep in the woods all by myself.
