I (and Da Bear) just left Tom on his way to the OR. They aren't anticipating any problems and he should be out of surgery by about 2-3pm and out of recovery by 5-6. I'm posting from the net terminals in the family waiting room, so I can't guarantee my access, but I'll try to reply here when he's out and resting comfortably.
He read all your posts just before they took him down to the waiting area and I think it really helped him to know how many people are out there pulling for him. I thank you for all your thoughts for him as well as me. We got a great community here and the bestest friends ever.
Keep those good vibrations coming!
