Spoken like a PCT hiker! I thought the same until I got exposed to the AT scene, where, it turns out, many hikers don't know or simply don't care what their packs weigh, saying "It is what it is. It works, so why mess with it?" There are also those who are proud of their heavy loads and think anyone different is "crazy", as in the title of this thread. I have also been trying, in vain, to get someone to define "a full load of food and water". The best definition I've heard so far is "fill up the empty space in the pack until no more fits." Water usually means three liters, no matter that your feet are wet from walking in pristine springs. Welcome to AT world!
