About 15 years ago, I was driving East across Illinois about 8pm on a Friday. Just outside of Joliet about 15 staties etc went flying the other way on I-80 with their lights blazing. I had a 1993 Plymouth Duster with a strong little V-6. About the same time I did it, a Camaro and I jumped into the far left lane and did 100+mph all the way to the tollbooths on the West side of Chicago. That trip I made it from Omaha, NE to Grand Rapids, MI in 8.5 hours. That's 650 miles and my road trip buddy and I stopped once for gas and food.
