From the website:
You've seen unwashed, malnourished through-hikers on the Appalachian Trail. You've heard about the grizzly bear wandering through the backcountry camp. You've encountered backpackers with tons of gear, pots, pans, and a folding stove -- eating some gritty greyish paste and raving about it.
And you want no part of it.
But you love hiking. In fact, nothing suits you more than a day in the wilderness, except perhaps, a day in the wilderness followed by vitello saltimboco in a four-star restaurant. You'd enjoy weeklong expeditions, if only you could jump in a car at the end of the day and head off to a comfortable bed.
Congratulations, you are a confirmed Slackpacker.
