Wow - more great stuff from the master! ^ I don't know what is more exhausting - the thought of taking your crazy mileage runs or writing them up in such intricate but entertaining detail. Anyway, I'm glad you did.
I have a couple of questions about the logistics of mileage running Seat 2A style, purely out of curiosity. Firstly, when sleeping in airports, don't you worry about the security of your stuff? Or do you entwine the straps of your daypack etc around yourself so no-one can make off with it? I remember when I was a backpacker I never slept well in places like that as I was always paranoid about my things being stolen. Secondly, and I'm not trying to be cheeky here, what about washing? Do lounges in the USA tend to have showers or do you have some other cunning solution?
