OK George, here's the best way to get to Wisconsin from Tennessee! Take I40 to Nashville and then I24 up through Clarksville to Paducah, Kentucky. Continue with I24 into Illinois, taking Hwy. 57 north to Effingham, to Champaign/Urbana. From C/U go west on I74 to Bloomington/Normal. Once there, take I38 to Wisconsin. You will avoid heavy Illinois traffic. But I warn you, there isn't a Waffle House outside of Kentucky! I39 is also the highway you'll take to the Camp-Outt. We take this to Monterey/Cookeville every time we head to TN. Safe journey!
