It's my ambition to travel with only my passport tucked into my pocket, not quite made it yet, but working on it, voluminous shirt with 'normous pockets - sold in Camping / Safari Holiday type outfitters called Magellan, 1060 Santa Monica Avenue, CA. topped with one of those photographers sleeveless jerkins with millions of pockets, and completed with cargo pants, also with millions of pockets.
Canvas 'money' belt with plastic buckle that I positively refuse to remove for the Gestapo - no metal, doesn't register, look, I'll prove it - and Crocs that can be kicked off for all the stupid security lines that one is unable to avoid.
I trattle and clank, and look like an " Anorak " - but who cares ? ( actually, I've noticed that my wife tends to get behind in the Duty Free, or Newsagent shops, and boards after me ! )
Still need a backpack - on wheels, with retractable handle, but working on it.
