Hello All. This is my first post. I have attended every AirVenture (I know they have not always been called AirVenture) since 1984. Every year I purchase a lapel pin. On my return home last night I placed my new 2013 pin on the hat that is far too heavy to wear anymore and noticed I am missing 4 pins. If anyone has a 1997, 1999, 2002 or a 2012 pin I would be happy to pay any reasonable price. I had a great time again this year and the weather was fantastic! Thank you.
