Tony & Ed, I hope this never happens to Laguna Seca, or Pacific Raceways, I've raced at both tracks with Portland & Thunderhill thrown in.
All true road courses, that can ever be replaced by temporary street circuits, hitting concrete walls in vintage cars never work out well for the car. So don't get me started on this issue.
Even though I'm retired from racing, I still have plans to see racing @ these tracks, lets wish them all well, and if I every start acting like a 'Karen' somebody for god's sake drop me like a 3-foot putt 

 Cheers TommyRot.
