Growing up my dad always dreamed of owning a 57 chevy bel-air. He grew up poor in a family of 7 children. He never thought he would be able to own his dream vehicle but would talk about it all the time.When I was 8 years old I promised him that on his 57th birthday I would buy him a 57 bel-air. I never forgot and was able to fulfill my promise.

By the way, offspring who promised to invent cold fusion, make millions of dollars and buy me a Winnebago (you know who you are) - I'm still waiting.
