Woke at 0400 hrs to find that on Sunday morning the 12th Oct that at there was heavy fog. Set off anyway in the dark icy fog heading for the last event of the season at York- over 5 hrs much of it in the fog.

 Was hopeful that engine problems were now rectified. Saw the sunrise on the A66 heading for Scotch Corner and the start of the run down the east coast to York.

Got there to find that the fog was even thicker at the track. Waited until lunchtime but showed no sign of clearing. Headed back for long drive and found the fog had cleared on the M1 but too late to turn back; plus I had no way of knowing if it was still bad in York.

An unhappy end to the season.
