Notice that both the left tires have light under them.
An inch or two. That's how the car corners. Carries the inside front tire, sometimes 4 to 6 inches, and on real hard turns, like the chicane, bumping the curb will get the car up on the outside tires. I (and pretty much everyone else there) sometimes got the high side a foot or so.
Not quite like Joie Chitwood, but close. Stay with it, turn into it slightly to get it back down and it hooks up. Squirts the car down the straight to the next turn.
Awesome fun.
Even when one goes over the edge.
