I'd buy the QE2 and recommission it. Come sail away, come sail away. St. Jude's on the water. Entertain and give joy to the kids and their families. Full medical facilities, the works. Probably cost $500 mill to redo.....bet I could buy the ship for a dollar. I know a few folks. Two of my brother's worked on it in the 80's. They did 8 world cruises + the other trips.
build a 10 track motorcycle park in a state where it would be super cheap to make it really nice. Charge fees for what it costs to keep operational, no profit. and put a hooters in it
Im still lifetime up on the lotto (powerball actually) after my $10K win several years ago. Hoping to up that lifetime "earnings" tonight.
