I'm planning a road trip this summer 2010 from Sioux Falls to Chicago through Omaha, Des Moines and Moline from Argentina.
I've found your site very helpfull.
We are a group of 24 argentinians farmers and we are visiting local farmers and Universities. We'll rent 4 minivans at Hertz.
I am looking for touristic advices, things or places to visit or see while we are on the road.
Thanks to you all
