I remember during a rain delay at Fontana there were a few random long shots of the pits in which there appeared a man casually taking it all in dressed in a yellow bathrobe and bathroom slippers, with the quintessential cup of coffee.
I forget if it was here or on the NASCAR.com chat room, but a few observant souls were like hey, who is that guy just wandering around in his bathrobe?
Well I just saw a commercial that I believe finally explains that puzzle. It was on the pre-all-star race coverage on SPEED.
For the record, no there were no cameramen in the shot that appeared to be filming bathrobe man.
