OK, I'm going with a couple of coworkers up to Naperville. We're in Champaign, so straight up I-57 and it Google maps says it will take us 2.5 hours. We can leave anytime we want, I thought we'd leave around 2 to get there around 4:30 and we should stay pretty clear of traffic, right? Now... my parents think Rt 47 is the way to go. That feels SOOO slow. Googlle maps says that will take like 4 hours! LOL. What way do you think I should go?
