Ah, Summernats. I used to work at a servo in Canberra. That time of year was nuts.
Usually I was the only staff on site, but we'd have four staff on for nats. One would basically be handling the car wash exclusively. Two would be constantly restocking food and drinks. We'd get a shipping container of extra stock dropped off to keep up.
The bus home would have to go through a cloud of tyre smoke, and half the passengers would get off at the north side brothels and strip joints.
I never actually went to the festival itself, but I feel like I got most of the experience.
Two movies that usually appear on lists like this, but I don't see them: The Fountain, and The Fall.
