Anyone that has been to an airshow anywhere else in the world will realise just how substandard Avalon is. It is not the acts themselves, it is the dictatorial attitude of the 'airshow boss' or the 'ringmaster' that ensure you have acts separated by 30 to 40 minutes. Why? If you attend Oshkosh you will see 4 to 5 acts at any one time, separated by altitude. Not that hard.
Fly into Oshkosh in your own aircraft. You will wonder why you were so anxious prior to doing it. It is an ego free zone, incredibly professional yet incredibly friendly.
Driving into the Avalon Airshow, 2 to 3 hours, come on, driven into Oshkosh? 100,000 people driving in for the bigger days and you can be on the flight line in 30 to 40 minutes.
I'll be going but I certainly wouldn't be if I was paying to get in.
