Well today was the day we have been waiting for with some excitement and some concern.  Today dad had a CT scan then met with the neurologist.  The news was even better than expected.  Dad's brain has no signs of damage or "pockets" of damage so the neurologist see's no reason why he will not make a full recovery with "time".  The brain heals very slow but it does and so far he is making the progress he needs.  Physically he is coming around partially due to his PT but he also has a personal coach who keeps pushing him if he likes it or not, way to go Mom.  Mom and dad continue to live at Scott's but now that dad has been cleared to fly I know they are looking at getting down to Arizona to get out of the cold.  Dad has a couple more weeks of in-house therapy then they will evaluate there next steps.
