Ho hum. Been doing it my whole life. Gear has gotten lighter and fancier, but to tell you the truth ...
standard equipment when we were young (literally) ... axe, cast iron skillet, side of bacon, full ham, a few zucchini, small watermelon or several cantaloupe, dry rice, fishing gear, sleeping bag,etc. Typical first day ... four to six thousand foot grade over twelve miles in two hours! Those were
the days! Now that I'm well over sixty, I've been reduced to buying some of that fancy new gear and am clear down to a pitiful little 65lbs pack, and slogging along at about two miles an hour or less The trick is to keep moving, stay in shape, and truly enjoy it. For a beginner, just hang out with some ole worn-out geezer like me and learn the ropes a step at a time.
