I was lucky. My father-in-law-to-be ran a machine shop. He machined
me the most beautiful heat sink you've ever seen ;-)
He also planed the head on my '53 Hudson Jet after I warped it by
over-heating the engine and blowing the head gasket. Made it pretty
speedy... I could get 100MPH out of it ;-)

I love to cook with wine. Sometimes I even put it in the food.
