I did this once. In college, I worked security. On the 4th of July, we closed off a road behind campus because of the danger of fireworks and dry grass. I manned the entrance to the road diligently. A Buick came up and tried to enter. I said no. The driver sternly warned me-- "Do you know who's in the back seat? The mayor!"
I let them pass.
I watched FP1. Hard to get used to the new sound of the engines (or the lack thereof). They sounded like flying saucers.
