If you haven't heard about the Seething Sardine Festival or associated events, where have you been? Seriously? Thousands of people from across London trek to suburban Surbiton to take part in the crazy community events which have included giant games of mousetrap and pop-up pirates, and steam punks and children in cycle races on Penny Farthings. It's kind of unusual but it works - devotees get their community fix, and the creativity and imagination of the arts crowd gets an outlay.
