Depends on the meeting type. If you go to whichever one involves the relevant committee or board extracting expensive concessions from mundane businesses you're gonna see more younger people because first time business owners tend to be the ones who get screwed the most because they blunder right into all the traps the system has prepositioned for such people.

I watched two brothers in their 30s who'd bought a 12-unit (they lived in it) go rounds with the city over all manner of petty bullshit that can be construed as a legitimate concern on paper but really isn't if you look at the totality of the situation. Ultimately they hired the law firm which was owned by a lifelong developer who was the head of the equivalent board in the next town over (i.e. someone who knew people) and suddenly none of those things were problems anymore.
