@bmo I’m assuming you’d have no problems nominating Baseball as our national sport?
Actually, choosing one for the US is quite hard since we invented Baseball (in its current form), Basketball, and American Football (and probably some much lesser known ones). I’d still place my vote for Baseball because it was the first sport to integrate racially, the first to have an ultra popular professional league, and it’s connection to the 4th of July and American national identity.
As for California, I already said our official (by law/decree) state sport is surfing. It makes sense seeing as we have some of the most famous surf spots in the world, and probably the most surfers per capita. I’d personally argue that Cycling, Triathlon, Athletics, or Pickleball be made the official state sport. Beach Volleyball, Volleyball, and Skateboarding would be in contention too. If we were to have an official winter state sport it would most certainly have to be Freestyle Skiing.
