Thanks you a lot for the information. Yes I have flown the C150 throughout my PPL, I like this aeroplane. But I am more interested in flying the PA28 to get some more experience with a low-wing design .
I have some time to organize since I can go there in the end of July at the earliest, so I'll do some more research.
Ideally, I would like to fly around the Midwest. But in case I dont find such an option, I guess Airplanes4Rent or FlightTimeBuilding would be a probable option.
A question to anyone reading this thread, do you know of any reliable company renting aircraft in the Midwest? Thanks
