I'll make my own way as I'm already well outside of London. Meet you at Oxford train station so long as it's going to be dry on the day.
Edit: as the meet-up point has changed, I won't meet you at the station!
So far the map doesn't give the suggested route. As I'll still be arriving by train, I have yet to find the meet-up point.. There's a Gloucester Lane and Gloucester Street; where's Gloucester Green? Is the meet at a coach station or just a coach stop sign on a lamp-post/bus shelter?
Edit - OK, seen the google map attached to the flickr group thread,... should be able to find the coach station, then I'll just look for a group of people carrying cameras ! Should be some familiar faces too
