I had an enjoyable day last Saturday at the National Museum of the Air Force at Wright Patterson AFB in Dayton Ohio. I had never been to this wondrous place to see air history. Everything from a Wright Flyer to a Stealth fighter is there. All of the classic planes from WWII are represented and all displayed wonderfully.
I highly recommend a visit to this gem of the Cincinnati area. It's free and the only requirement is that you be sure to wear comfortable shoes and allow yourself plenty of time. There's so much to take in here, you will be amazed. Well worth the trip up I-75.
