Butler Co Regional Airport

Not sure if it is still being hosted, but local legend Martha Lunken used to organize an annual Wings Weekend event at Butler County. I would fly in annually from OSU (who now hosts their own similar event, but I enjoyed the simple flight down to build up cross country time.) Was a fantastic event. Instructors donated their time to help keep pilots safe as part of the FAA's Wings program, which counted as a biannual review. All you paid for was your flight time (they even paired you up with a plane if you drove in.)
