We used to have the autumn crawl after half-term, but this had the disadvantages of colder weather and early darkness. Half-term holidays seem to be the week commencing 25 October, which means Friday 22nd is likely to be busy on trains. September is a bit soon, isn't it? (And I'm plannning holidays as schools will have gone back: I can't make either 10th or 17th.)
Several people have already said that Friday, 15th October would suit them just fine. Shall we go for a general acclamation, given the fact that train tickets are already on sale? Or should we do a quick poll?
