Thinking about the London-trip-to-see-people-who-I-won't-see-on-my-next-London-trip-cos-they'll-have-all-buggered-off-to-Whitby (LTTSPWIWSOMNLTCTHABOTW for short). The most likely looking date for LTTSPWIWSOMNLTCTHABOTW is the late May Bank Holiday (weekend of the 28th) - but would this mean I miss anything unmissable in Leeds?
