At present time it is scheduled for July 24-25, not too long ago it was the 17-18???
http://www.prairieair.com/In Feburary I was in Bloomington, IL for the DC3 ground school and I really like the area, and the people at the Prarie Aviation Museum were a great group of people!! Really made my time in Bloomington a great one! They told me about the show otherwise I wouldn't have heard of it, but because of the friends I had met there am making plans to go back! That and the Angels!!!!!!! Not to mention the Ozark DC3!
I think it would be great to meet up with some fellow simmers! Since I have no idea yet as to the layout of the show I wouldn't have a idea where to meet! I'll see if I can get a map of the layout and maybe post it so we can pick a meeting area!
