What a day. From the flight down, the clockwork flow of travel in London - including the comical announcement from the tube driver for why he had to stop his tube in a tunnel for a few minutes. A good PC World, food street market and a laze around Finsbury Green waiting for venue to open. And what a first day!! I went to the "in practice" hall and came away with 9 pages of notes and a head buzzing with ideas. Day 2 tomorrow. Bring it on.
