Oh Happy Day! I'm going to London next week. I've managed to book a hotel for one night in Bloomsbury just 5 mins away from the British Museum. And my other half is going to be heading off for a meeting with his agent, so I will be at large on my own in London for hours. BRILLIANT!!!! I wonder how much crap I can carry? Camera and lenses and batteries and a gorillapod. A leatherbound notebook, 2 pens and a pencil. A Moleskine London edition. A bottle of water. Probably a handful of tickets and receipts and random colourful bits of paper that I accumulate along the way. The Guardian. A big square scarf. Maybe a little ipod, probably not. So my question - What "essential" stuff do you carry?
