Yep, all this high tech pack stuff reminds me of a tv show I was watching about the Maori, where one fellow was packing most of his belongings in a shoulder pack (I say shoulder pack only because the hide bag he was using only had one strap, which was draped over his shoulder) over the hills to another village to trade. When he got there, many of the items he removed were carefully wrapped up in plastic grocery bags, which he carefully unwrapped, folded up, and stowed away for later. It is amazing the contrast between his priorities and those of our throw away society.
