Hey Joe!
Nice shots.
Last month I was going to shot a Rally at Night, but unfortunately I couldn't go that weekend, so I missed the action. Great captures. I'll have to wait to get a night race to shoot at. Think could be intresting.
In January there is a 24hr race here at México, but there's a chance I will be driving, if not, I will try to get some shots.
BTW, if didn't use flash, where the light on the side of the car came from? There was lightning on track?
Cheers.
