I'm a couple hours south of there, not a cheap drive with my old gas guzzling pickup.
But you should know that Davenport is in Iowa. It's part of the population center known as the Quad Cities -- Rock Island and Moline, Illinois, and Davenport and Bettendorf, Iowa -- which together straddle the Mississippi River just north of the mouth of the Illinois's Rock River, and where Interstate 80 crosses the Mississippi. If there's a Davenport, Illinois, it's not on the state map.
