i did two weeks of backpacking and climbing in maryland/pennsylvania in june/july 2004. although it was physically the most intense and difficult thing i’ve ever done, i proved to myself that i can really handle anything as long as i put my all into it. i know it sounds cliché, but it’s true. the 48-hour solo was really intense, so i advise that you ration your snacks so that you won’t go hungry (all i was given was an apple, a handful of trail mix, and a granola bar), and afterwards, you’ll appreciate your toilet and shower WAY more than you ever believed possible.
