My two cents:
I went to Oceana this year too. To me the Military airshows are not geared towards the "aviation fan" anymore. They are geared towards the everyday person. The only reason I went to the show was to see the Snow Birds. I did enjoy the military demos, but all the other stuff I've seen before. I mean honestly, how many times do I have to watch that jet truck go up and down the runway.... Also, why do I want to wait 2 hour in traffic to get in and 2 hours to get out, then have to take out a small loan for sub par food that only makes you have to use the dirty port-o-johns? I know it has its own issues, but to me Oshkosh will always be the mecca for airshows (at least here in the states).
Like a lot of things in life, The Simpsons said it best: "airshow?... What kind of country-fried rube is still impressed by that?"
