Well, they used to fly to Dubuque -- I checked when I made the OP. Orbitz now says there is nothing from Chicago on the dates I chose in July. The airport webpage says they only have charter flights on Sun Country.
When I ask American to get me to Dubuque, they propose to fly me to Madison, Wisconsin. That's only an hour and a half drive.
Southwest flies to Des Moines, and then I don't have to drive across any big rivers. Three hour drive. My great grandfather was from Des Moines. I don't know who these Gilchrist people are, though.
