Oh, come ON. In some states the legal age for beer is 18, so the kid will be perfectly legal I believe in Wisconsin.
Nope. Drinking is drinking, and our drinking age is 21, despite the Tavern League being one of the most powerful forces in our state's government.
And, I don't think any states have any drinking under 21 any more, even just beer, because they have to forego federal highway funding if their drinking age is less than 21. Been that way since 1986.

You are from what century?
Careful, you seem to be from the century where 18-year-olds could drink in the US.
..Osh is just like that, but replace the self-check kiosk with a Garmin, Dynon, or Avidyne booth. And replace the 4 lost old souls with tens of thousands, 50% of whom you can see their nipples through their threadbare and faded T-shirts. There are also a few dozen bored-looking females, all of whom can remember a time when they didn't have the right to vote.
Wow. Maybe you should stop hanging out in Vintage.
Or come again...
FWIW, my first Oshkosh was in 1987, when I had just turned 13. I have several enduring memories of that show, one of which was an old guy - OK, he was pretty much a fossil - Complaining that "REAL airplanes want to fly, but these dang nosewheel things, you've gotta PULL 'em off the ground!" And I don't remember any pretty teenage girls.
But, these days there are a lot more women at Oshkosh, and not the fossilized variety. Some are pilots, some are wives/girlfriends, but Oshkosh is quite family-friendly these days.
There's also plenty of young people. It's not a Taylor Swift concert by any means, but IMO it's not at all as you describe.
