Via mi amigo Ed @ Ed's Manifesto:
"Friend of the page sent in this picture. He arrived in an unfamiliar place and went with the on site procurement method. Basically he built his cheap throwaway kit from just one trip to the Local Walmart. This method allows you to bypass a lot of problems as far as transportation of gear from one country to another for example." - Ed
Commentary: Sometimes circumstances separate you from your tools. Air travel is a big 'un, especially if you're packing light and limiting yourself to carry ons. A little cash and improvisational ability can get you re-equipped in no time.
Or plan ahead and cache it.
I'm seeing maybe $40 worth of stuff here, but well rounded set for daily carry.
