Theres brothers Bill and Frederick still around. I watched a highly entertaining movie the other night ; a documentary from 2016...Sour Grapes. A segment of the movie involved an interview with Bill showing off his 40,000 bottle wine cellar in his home. Great flick.

The only satisfaction I may get is knowing that when the Revolution comes, the Kochs will be first against the Wall.
