i just emptied my Deuter 30L bag after i came back from US, and i found a big stack of vietnam travel brochures in the backing compartment of the bag! that compartment houses the bag backing that keeps it upright, and i never put anything into it, so i never checked it. i also found a ticket to a sanctuary dated 20 Dec 2007, matching the date angdao went vietnam.
i just carried the bag (plus the big stack) up to one of the waterfalls in yosemite park!
