I just saw a piece on REAL Sports with Bryant Gumbel. It was about a 5 year old golfer named Kyle Lograsso. If you have HBO it is the 3rd piece on the current running. His longest drive so far is 172 yards and has shot a 42 on 9 holes.
It is probably one of the most heart touching stories I have ever read to date. You can probably Wiki him, but, if you watch the piece, you'll understand.
