Riding the Wall of Death Allan Ford
By the 1980s you would have needed to go into Europe to find one in operation until a resurgence of interest in running them took place in the UK. One man who was a part of that renaissance, Allan Ford, a past rider of the 'wall,' helped resurrect not only the walls themselves, but general interest in them.
This book chronicles the whole history of this fascinating branch of motorcycling. It manages to convey why the 'wall' has always attracted audiences that still keep coming back to watch riders at 90 degrees to the wooden sides that sway and shake as the bikes cross the individual timbers that make up the cylindrical track. It also mentions the variants such as the Globe of Death and the Cycle Whirl, and is as much a history of entertainment as of motorcycling.
If you have ever stood at the top and had the riders pass inches below you, apparently defying the laws of physics, and wondered why and how then this is a must-read book for you.
