remember my dad telling me ..he was out on a sunday afternoon on his motorbike, came up behind a large group about 20 pushbikes all dressed up in their racing lycra, taking up the whole of the lane .. road opened up as he went to over take em , one of em in the middle of the pack came off , dad said it was carnage , they all started coming off falling all over the road...if they want to race they should go hire a race track.
