Alf was right - I guess the geographical clue was pretty conclusive - the next Big Day Out witll be to destination no. 163, Reading. I'm strangely excited about this simply because it isn't too unfamiliar or intimidating, and a quick look at Wikipedia suggests there'll be plenty to do, not least with rivery themes.
It won't be until after Braunston, though, that I'll be able to get away - at least, I don't think so.
