You don't have to go through MLI to get to anywhere, so
kind of out of the way for the 'travelers' that frequent FT, but, if you happen to be in the QCA (Rock Island, Moline, Davenport) area, you might try Whitey's Ice Cream. Locally owned and made in Moline.
Not cheap , only the best. http://www.whiteysicecream.com/ourmenu.asp
