If you're at the track, please remember that if you hear thunder, you are close enough to be struck by lightning. When thunder roars, go indoors!. Have an umbrella handy and pay attention to the PA announcer. Road America does a great job in alerting fans and teams of inclement weather. But don't let that deter you from attending the great racing action. Rain only makes the best drivers in the world shine, and you'll have an opportunity to see that happen.
