I'd love to camping, hiking, etc. but my (admittedly few) experiences have been... less than enjoyable.
Most of what I've done has been "difficult-environment" Geocaching, meaning no more than a couple hours or so away from the car, but in below-freezing temperatures in the dead of night through swamps, dense forest, crossing large-ish lakes and streams without a decent boat, etc. and I've had a blast doing it...
but the only comparatively "real" camping experience I've had was when a friend and I tried to climb a mountain in CO in the middle of summer. I only lasted about half an hour before I couldn't go any farther, and we set up camp. That lasted until about 8pm (!) when it got so cold that I simply couldn't get any rest. We ended up scrubbing the whole ordeal, me losing a friend in the process.
I can walk for miles with regular everyday clothing and shoes, with no special prep at all, on flat terrain. I don't consume large amounts of liquid. I'm decently strong, and can carry a good amount of weight for a long period of time. I'm not afraid of heights, wild critters (if properly armed), darkness, or being lost. Left to my own devices and with nothing more than a halfway-decent fixed blade knife, I can set up a decent shelter and probably not die. I can read a map and use a compass to figure out where I am. I know rudimentary first aid skills, how to signal for help, and so on.
But I cannot hike on any kind of gradient, apparently, nor can I seem to keep warm in the middle of the summer.
I really, really want to, but it seems that I cannot. Not without spending thousands of dollars on equipment and clothing, which I've never been able to afford. I think, in the end, I'm not built for it. The mind is intelligent and the spirit is willing, but there's too much flesh. Maybe if I just tried to do it with no gear at all...
