Date for PuG crawl in Cambridge.

[Tris39]

Also leaving it until (much) later decreases the chance of reasonable weather.

It looks as though the extra votes for 28th were Spinko and Tris.

Pushing it from 28th forward to 11th November will make negligible difference to the weather, unlike mid-January, but mid-October will mean a gap of five months until the Spring crawl.
