I got the book itself, can bring to manc National and you can scan it.
Trivia. My workshop was Don's workshop many moons ago.
When Don aproached us whilst we were riding at hollow ponds in 1978 we thought he was a bit strange, then he brought a full suspension bike for us to try out 'DS SPRINGER' (it sucked but was way ahead of its time)
One of the riders featured in the book gave up bmx right after the book was published, he has just started riding bmx again and shared the gate with you at Braintree on a wednesday eve last summer.
Useless trivia, but trivia
