I'll just share some lighthearted commentary now.
When I was learning about racing, I didn't know NASCAR raced around road courses until I played "NASCAR Racing" for the PC that featured Sears Point and Watkins Glen. And of course, back then, NASCAR mostly raced what is the Sports Car Course (to use Gran Turismo 4 as an example). Anyone who is fairly inexperienced with NASCAR and road racing- yes. They do road race stock cars. It just isn't done often. I love watching stock cars go around road courses as well as hearing the cars hammer through the gears. As someone who grew up with GT/sportscar/endurance racing, I do admire NASCAR drivers for road racing. Ovals provide great drama and action, but there's just that little-bit-more that makes road racing a greater challenge. Some people even think the Chase for the Cup should have a road course. While Sonoma is a great course, I will ALWAYS remember when NASCAR Nationwide raced at Circuit de Gilles Villeneuve with rain falling. That was incredible! Most impressive about some of those races was NASCAR's inventive ways to road race stock cars in the rain. It wasn't perfect, but I applauded NASCAR for finally testing their road racing rain deal as opposed to delaying a road race out until the track dries.
I posted these musings just to get some of the ones not real educated on NASCAR to care about seeing NASCAR road race. I usually favor Jeff Gordon in almost any race. I especially favor Jeff Gordon because he's one of the best road racers in NASCAR. He once had a wicked win streak of about five on road courses.
Good luck to all NASCAR drivers this weekend, regardless of where they race.
