Great little story that. It reminds me of a few years ago when I was 1 of 10 man army team who ran in 13 mile relays from Lands End to John O'Groats in aid of Marie Curie. When I got home, I told the missus that I was going out for a little shake out run and came back nearly 4 hours later, she did her nut thinking that something had happened to me No where near what this guy did.
And I am sure she just sat at home waiting for him to land .Must have a fair wedge to disappear for that long but good luck to the dude it's perhaps what we would all like to do for a short while (just escape ) from the daily toil of boring work!
Nothing on this scale, however Bats and I got talking to a bloke on a GS at Hartside one Sunday, he being a single retired gentleman thought nothing of "his words" popping to the shops for a pint of milk, and thinking oh stuff it let's see how far I can get, ends up on a ferry and spends a summer riding the length and breadth of Europe. He told us all the aluminum luggage was always packed up ready to tour, just in case he had the urge.
