A few days ago, I started a thread called "Three Things" where I asked folks to come up with the first three things they'd tell a prospective thru-hiker about their upcoming trip.
The responses so far have been great.
Along those lines, if there was ONE thing about the Trail or about thru-hiking that you wished you'd known about BEFOREHAND, what is it? In other words, what's the one thing you wish you hadn't discovered by accident?
