Hello,
I've enjoyed reading this thread. The "why" question feels particularly relevant to my current situation as I contemplate various life decisions and evaluate how my interest in the outdoors might fit into those decisions. Whether one approaches their relationship to the outdoors in practical or spiritual, pragmatic or religious, individual or communal terms, priorities are always at stake. To be in the outdoors is to NOT do something else- and of course there are only so many days in a lifetime.
Something that has not been mentioned, but which I think is nonetheless important, is that being in the outdoors involves not just personal choices, but the very availability of those choices, and opportunity to make them in the first place. This tells us that the evaluation of personal motivations or preferences will never be, by itself, sufficient as an explanation for who ends up in the outdoors and why they do so. For many, venturing into the mountains or desert is simply not an option, and has little to do with whether they might "choose" to do so. The question "why," therefore, is as much political as psychological. We do not live lives solely of our own making. Even categories like "nature" are not neutral, universal, and self-evident. Few landscapes on the planet are not, in some way, anthropogenic, and the opposition between nature and culture/civilization is culturally specific, and by no means shared by all people everywhere.
As for my personal motivations, I think much of it has to do with the clarity of purpose and focus which comes with being outdoors. A schooner captain once told me there were journey people and destination people in the world. Sailers were the former, and power boaters the latter! My guess is that most hikers have a fair bit of the journey in them. Something special happens, for me, on the journey. There is a clarity in determining my next task, or my next step, and in staying attuned to my surroundings. If daily life is characterized by so much ambiguity and distraction, the journey clarifies where I am and what I am doing. Daily life seems to require mid-range vision, neither focus on what is immediately at hand or what is most distant. The journey, however, allows me to simultaneously appreciate the smallest details and meditate on the horizons.
And since I live in Boulder, garments possessing superior moisture management properties are a potent aphrodisiac with the ladies (hee hee).
