Here is my video from the event a week ago. I finally got an external mic which I hook up to my GoPro that's mounted on the bar behind our seats. AK370 has a nice writeup on how to make a custom mount there that doesn't cost much and requires one quick trip to Home Depot. I also tried a new spot on the outside of the car, right on top of the roof. Gives me a bit better sense of how close I'm getting to some of the cones.
