It’s baseball season. Go to ESPN and look up the box scores and any special plays. You don’t need to know your local team at all because it’s probably blacked out on tv anyway.

If you don’t know baseball, ask questions about bocce ball or pickleball. Americans will literally tear down their large community trees to build these.

Outside of sports, gardening or birdwatching is another good area. Everyone admires those who do it, but few are actually any good at it, so odds are you can make some shit up as you go along and they likely won’t know but will nod in agreement anyway.
