I started last night to list everything that I feel that I should take. Inevitably it would possible to increase or reduce this list. For the hardened traveler, you will say that this is far too much. For my wife, it will never be enough, but that's ok, since there's only room for one in my bivi-bag.
I will amend this regularly, so for the moment please view this as version 1. A very rough brain dump for the moment.
