thanks ken really enjoyed this. by the way in school i just got a brand new 10 speed bike . i was riding it up my street really getting in to the algarythums of peddling. feeling free and dreaming of flying. with a hugh jolt i now found my self laying spread eagle on top of a parked car. looking ot my left i could see the faces of a family having a reunion on their front lawn. they looked quite bewildered and i was completly embarased. it was the early 70s so i might have some excuse. not sure what catagory that puts me in but somewhere in the knowlege and understanding watching where you are going must play a hugh part?
