Unpopular opinion. I'm so frustrated I hate car shows/cruises.

First of all, the term "butt hurt" seems to be a Millenial favorite...a stupid term that annoys many people.
Secondly, if you're discouraged and disappointed with the situation, what are YOU doing about it? Have you joined a club and made suggestions to liven up the agenda?
Change may take time. Ask around about who is a drag racer, a drifter, a road course guy/gal. The motorsports aspect is always going to be more involved with their cars than the "lawn chair behind the car at the car show crowd".
I'm a member of a Sacramento Mopar club. There are some OLD members that do almost nothing in the club but there are a few around 30 that DO.
well, last time I looked in the mirror I’m one of those gray haired guys. Hopefully you are not complaining in front your kid. That’s a quick way to lose him to other, mote unsavory hobbies. I have to agree. Take the bull by the nads and start your own events. You would be surprised of the other like minded guys and gals who will follow. Even some of us gray haired guys.
