Oh, and I'm in favour of doing it at the weekend - and presenting it as a celebration of cycling as well as a protest and a memorial. Tea_bee's point is a good one - if the initial ride makes a big enough impact, all future rides will be associated with it. And - although I hope no one will ever be killed again - a (slightly more disruptive) white ride in the wake of every fatality will probably do much more than the ghost bikes to bring this to people's attention.
