Just had another thought, I joined when I lived in Staines which is also 30-ish minutes out of London (Waterloo) - so I guess about the same time from home to Euston as you would have.
Most of the members are not from London as such, but are scattered around the south East and meet up in London. We also meet before Saturday 3pm home games from 12.30 onwards at the White Friars.
