I am seriously thinking of driving to Clinton this summer for the fly in. It is a long way to drive but I am sure the airplane will be gone so if I show up there it will have to be by travel on the highways.
You can fly commercial to Quad City/Moline (KMLI) and someone will fly/drive over and pick you up. I just checked and round-trip ticket Salt Lake-Moline departing Monday July 17, 2023 returning Sat July 22. 2023 is $578 per person. Driving round-trip will be around 2500 miles; not sure what gas mileage your vehicle gets and the price of gas then, plus maybe one night at a motel each way.
