Thanks to both of you! The NASCAR site didn’t answer my questions and you both were clear and concise. Thanks!
Nationwide race is on today! You will see a lot of drivers that will be racing tomorrow as well.
BTW, my son is a huge F1 fan. I've watched quite a bit of it as well. Interseting that a lot of "open wheeler's" are migrating to Nascar. What a shock they must get the first time that drive that big 'ol lead sled......
