I'm not sure if this is the right forum, but I am guessing someone here could answer my questions. And I guess they might be 'trade secrets' too, but I'll ask anyway.
1. Why do they pack the track in the clockwise when they race counter clockwise?
2. When I was much younger, I don't remember nearly as many dry slick tracks as I do now. What's different? The dirt? Cars? Car counts? Tire's? Chemicals? My memory?
3. Another one from memory. Black clay tracks seemed be start out stickier and not change a lot during a night, but red clay tracks seemed too slick and sloppy to even run the heats, but were hard as pavement by the feature. Why?
