It was a summer day at Pensacola Beach spent with family and friends.

Cory Jackson dashed across the sand, dived head-first into the Gulf of Mexico and hit his head on a sand bar.

When he resurfaced, he couldn't move. Three vertebrae were broken. His spinal cord was bruised. He couldn't move from the chest down.

From that day forward -- July 3, 2005 -- Cory would be paralyzed.
