I think the changes will be a good thing, especially taking out the lower rows where debris is likely to land. I think they said that they were adding new seats higher up, but that's just bluster to conceal the fact that attendance is down.
They just repaved so there's no chance of reducing the banking and getting rid of restrictor plates. It seems like a bad decision not to do that but I guess they didn't have the cash at the time. I'm glad that they have to do this with their own cash and I'm on record as not in favor of any government entity subsidizing the creation/maintenance/upgrade of any privately owned sports facility.
Daytona Speedway is the figurehead for stock car racing and needs to keep up with the times. I'd rather that they improved things for the average fan, but I know that the majority of the money will go towards suites, TV facilities and retail outlets.
As for the "$600 million five-year improvement program for the 13 ISC tracks", I don't believe that there will be any major improvements anywhere but Watkins Glen. Darlington isn't a major market, Martinsville is already perfect, Fontana, Kansas & Chicago are boring tracks that won't last through the decade. But if there's a hint of Formula 1 money coming back to Watkins Glen, ISC will be slobbering the same way that Indianapolis did.
