Been doing that for decades, and completely agree.... the best part of the whole thing - sitting on the bleachers watching hundreds and hundreds (billions and billions?) of planes landing two and sometimes three at a time. Listening to the sometimes confused pilots and tower personnel on a handheld while watching the ground crews keeping things organized and moving.
The airshows are the least of the things I want to see. The three times I've been to Airventure I could see as much air show as I wanted from my camp site. I just like being around thousands of airplanes, War Birds, Homebuilts, Kits, Vintage, and especially the ultralight area. The sound of a Radial engine coughing to life, the sound of a P-51 doing a flyby with the other WWII airplanes, that's about the only time I get to hear and see that. I have flown a T-6 from the rear seat, ridden in the bombardiers seat in a B-17, a passengers seat on the Ford Tri Motor, right seat in an open air kit plane, front seat in a 1929 American Standard Bi Plane and a Bell 47. But the airshows, once you've seen it a couple of times, well, it's ok, it's just not my thing.I only go to the air shows where it's free for everybody to get in.
What are you paying for, to see some planes?
I see enough of them every day and they say to me, why aren't you working on me, get done with that trailer already.
Certainly, in a perfect world you would attend both.I've met lots of men at Sun n Fun whose wife and kids were spending the week at Disney World.
Each event has its own character. I like both. Oshkosh will have many more military aircraft, Sun n Fun will have more LSA and Ultralights.
The best advice that I can give you is that you should go to both.
Still have the radio I bought at OSH many years ago that I use for decades walking out as close to the VOR as I can get and setting down and watching the airplanes land and take-off. I would go just for that. Problem with that, I have seem people get killed in crashes.Been doing that for decades, and completely agree.
