KCFly,
While in high school, my daughter was involved in the school bus accident in Georgia on the way with the chorus and band to sing in perform in Disneyworld. The driver fell asleep. She had some bumps and bruises but several of the kids had disfiguring "road rash". She had severe nightmares for many months and needed some counseling. I am not sure she has gotten over it!

I am telling you this as warning that the effects of the accident on your son will continue for a long time and you need to prepare for that so you can help him. Good luck. Your family zand friends are in my thoughts.

Regards,

Keith
