on November 26, 2004

A second and third pass showed that the track surface had gotten
too cold (38 degree) to hook well, so I packed it in for the

The clutch was replaced under warranty after about 125
Back to the track on Sunday. Hoping for warmer weather and better
traction. Best regards to all.
