On this page there are some various pics from walking around Airventure. You cannot see Airventure in a day - trust me. There is too much to see. Besides the airshow, there are hundreds of displays, vendors (inside and out) fly-in aircraft to check out, the seaplane base, the ultralights ... too much for a day.
If you take several days, watch the airshow, and cruise around during the morning you have a good chance of seeing most of the show. Oh, there are many forums and guest speakers too. So you better take the week and get it all.
I spent most of my time in the warbird area and was only able to briefly walk around and see what they had. It is an impressive layout.
