Yeah - Charlie Munger is an LA guy (though recently Omaha too, to an extent) and yeah he's crazy wealthy. He basically built Harvard-Westlake High School in Studio City, which looks like a really nice D3 college, just with better athletic facilities.
Munger, Tolles and Olson is still one of the largest law firms on the West Coast, and if I'm not mistaken, either Tolles or Olson is also an M grad, but I can't remember which one.
I remember reading about a bet Charlie Munger had with Warren Buffet on a Michigan-Nebraska football game, and I'm not sure if it was this last year or the year before. Apparently they have a fun rivalry with those two schools.
