I attempted a thru hike in '04 and while I was in Damascus I did hear rumors of packs getting jacked here and there, but I was smart, I never left my pack anywhere. The only time I left my pack unattended I learned my lesson, the sidetrack was kind enough to put a huge rock in it.
So if you leave your things out in the open don’t be surprised if they are ne there when you get back, oh well, deal wit it. And don’t go taking your frustration out on the people along the trail. They, for the most part, go out of their way to help hikers anyway they can, How many times have you come to a road crossing asnd found a cooler with food in it for hikers. Think about that next time you feel entitled to have anything you need just because you’re a hiker.
