On Channel 4 at the minute - bloke goes to the North American wilderness for 3 months to see what happens.
So you've got a week to prepare, £1000 to buy stuff and an 85L rucksack to put everything in before you do the same...What would you buy and what would you do in the week before you leave? For arguments sake the weather is typical UK mid-autumn, a bit of everything!
(No need to buy a rifle - you get given one of them before the plane abandons you.)
