We have been to Elkhart twice, once to see our 5er on the assembly line, & once to go to the national rally. The first time we followed map quest & the GPS which took us from KC up to I-80, I will only go that way again if there is no other way to go. Like mdamerell said that mess around Chicago was a nightmare!!! When we went to the rally we went across I-70 all the way until it was time to head north to Goshen. At least in 2011 when we got into IL & IN, I-70 was pretty rough in places, seemed like anytime they had a road repair, there was a bump...and there were a lot of road repairs! While there, you might try the Blue Gate Restaurant in Shipshewana, it's Amish, and very good homestyle food. We had one of our meals at the rally there.
