With the time a Fab 4 show is normally completed I can't imagine them being able to add 4 cylinders after the Pro Stocks and expect workers and safety crew to want to work later.
Maybe if they give all pit income from the 4 cylinders to employees and safety crew they could pull it off.
If Pro Stocks are allowed to use up MY personal fan time giving them hot laps and heats I will no longer be able to go unless I skip watching the last two features because it will put my getting home too late.
I'll probably have to leave to get home safely after the third feature or sooner.
I also don't see 4 cylinders on their Fab 4 schedule?
So, what you're saying as that as a race fan, watching racing uses up your fan time.
