On Sunday, after a private brunch for old-time Berkshire holders, Buffett will lead a sing-along outside of Borsheim's, before he and Munger host a three-hour press conference.
While his well-heeled acolytes peruse Borsheim's diamond clusters, outside in the mall, Buffett has invited some of the nation's bridge, backgammon and Scrabble champions to challenge and entertain his guests.
