One arrest with loads of cops and several drivers trying to physically intimidate corkers by nosing into them with horns blazing.
Then up to Wellington Arch. along Park Lane and back down again finally arriving at Piccadilly Circus and doing a bike lift there. Then heading East towards the impromptu destination, the Foundry squat which is facing eviction. On the way there a rider was arrested and the police turned up with an estimated 30 vehicles, and they caused a lengthy traffic delay.
There were several reports of drivers deliberately ramming cyclists. I saw one woman cyclist knocked to the ground by a taxi. but the police don't seem at all interested in such things.
Apart from the incidents it was a very happy ride indeed.
