Marshalling at the HBBB mx track today I saw many things get lost;
A CR125 lost its pipe
A PE lost its seat
A Maico lost its chain (and Mr Ballard had a loooong push
)
A Hodaka lost every second shift
An outfit lost its spark
An XR500 lost direction
The track lost its moisture
Several bikes lost their riders
but no-one lost their smiles.
