Some folks down the lake from me are pretty rich. He owned Deluxe Check.....when checks were hot and he had that market pretty much to himself....and then sold at the right time. Made many millions. They had built the largest aluminum hulled yacht in the world (?) at that time, I think. ....and travel the globe with it....often flying to meet the yacht in distant lands for a sail. Seems to me he paid over 20 million for it...after a two year build. This was about ten plus years ago. Had a crew of about 7 or 8 and a chef that traveled with them, etc. They also owned BIR for their son (whom later died diving off that yacht). Nice people.
He would rather spend his days at the race track....and loved all things mechanical. Not sure where they are these days....but really nice people with waaaay too much money. I think they were living in Naples, FL and "gave" the track to his son's wife. Strange knowing someone like that. You would not know they were loaded like that. Not sure they were any happier than the next guy.....but they were nice folks.
