Saturday is show THE SHOW day. That's not to say they don't have an airshow every day but Saturday you get two. Shows start about 3 each day. One day at Oshkosh? That will make you dizzy.
Went there in 2011, camped from Wednesday to go home one Sunday. Wish I could go the Previous Friday and then watch the planes leave on Monday. The airport turns into a town of about half a million people. In 2011 Sean Tucker was just getting into his routine when the storm (there always is a storm) blew in. He was hovering his plane in the wind, you could see him looking down and just knew he was thinking "I can just harrier down and land" but he did it the legal way as soon as the front made it through.
Mud, I was pulling a trailer with my motorcycle. You really should take a dual purpose bike but if you're crafty you can make it around the mud pits, until you need to walk to the bathrooms. Just expect to be muddy while you're camping and do you best to take clean feet/shoes to walk in.
Exercise for Fred's sake! If you can go this year GO. If you're planning on future events, spend 6 months before getting your walking up. It is a shame that next to people HOVERROUNDS are next in the list of number of things. They are rent-able there and there appeared to be about 10 thousand of them. I saw a 60+ year old dude with an IVin his arm, bag off his leg, bloated like his system had just finally said screw it, obviously just outta the hospital running around on his personal hoveround. Oh and his early 30's Maxim model wife running around next to him. Must be nice to have money. If I had that kind of money I'd rent a much more considerate dude to run around with my wife.
ICE CREAM. Absolutely my favorite memory. Each day we'd sit about show center, I'd be laid back on the grass, backpack as a pillow, my buddy would nudge me with his foot and say "Wake up man, you're missing a wonderful airshow". I get off work at 3 so I'm programmed, it's nappy time. I'd wake to the sounds of multiple airplanes flying over, performing and the like. Then one day I woke, rubbed the sand out and remembered the Ice Cream stand not far away on the main drag. The best Vanilla waffle cones I've ever had. Went, bought us a couple and brought them back. Perfect treat to watch the show with.
Nothing like a night show. They have hi intensity lights on their planes, usually one that shoots off into the smoke. Well it just looks like they're flying around on rocket power, so cool. That twin engine Beech just glows at night, even from inside the engine nacelles.
Go there, ready to walk, in a crowd of like minded people denser then most Walmarts on Black Friday. Spend at least one night at the light plane field on the south and watch the ultralights do touch n gos.
I don't know if I'll make it back next year or 2016, but it's one or the other. Best dang airshow there is.
