There's another of LCC's Flash Rides planned for tomorrow (22 Feb). These have been orderly events with marshals and police in attendance, and this one should be the same. The plan is to ride from The Mall to Parliament Square and back, assembling at 6:15 and leaving a quarter of an hour later. The intention is to show MPs that the following day's parliamentary debate on cycle safety matters.
While you're about it, don't forget to sign the LCC's Go Dutch petition and The Times's campaign if you've not already done so, and get a friend to do likewise.
Remember this. There is a mayoral election this year and a national newspaper on-side: there's not been a better opportunity to make a difference for a long time.
