Dale,
I run a guest mechanic program over these two weekends and John A was the lucky winner last week. Fortunately as we had no issues the most technically challenging task all weekend was eating lunch! As a result John had far too much time on his hands having time to watch formation laps instead of waiting back in the pits ready to spring into action like a real mechanic!
This weekend, despite his CV including Formula 1, Indycars and Le Mans, not to mention running some kid called Andretti in F/Atlantic, John A unfortunately didn't make the cut for the guest spot so please don't get his hopes up.
