Iowa is known for countryside full of corn, views of the Mississippi and Amish colonies. It is boardered by Illinois on the East, Minnesota on the North, Missouri on the South, Nebraska and a little bit of South Dakota on the West. The Eastern edge of Iowa is delineated by the Mississippi River.
Along the Mississippi in Dubuque, there are so many attractions that it is hard to keep track. The National Mississippi River Museum and Aquarium is a great place to visit. Their website has lots of information and they will be more than willing to send a printed flyer. Further down South are the Quad Cities (Davenport and Bettendorf Iowa, Moline/East Moline and Rock Island Illinois).
