I'm thinking of going back to Airventure on Sunday. What can I expect for closing day? Are most of the planes already gone or departing? Is it worth it? We like walking the grounds and photographing the warbirds, private planes etc. The airshow etc isn't important to us. I just don't want to waste a trip. I recall going to a county fair on the last day. Most people were packing up, few animals etc and felt it was a waste.
