Received an update from Charles:
"He was up with his eyes open responding with a thumbs up to questions this morning."
(At least we know our little nomadic friend can still hitchhike)
Charles is going to see him tonight after work.
Should have more details then..
UPDATE: For those that did not read Charles' comment below,
the surgery was postponed due to the fact that he contracted pneumonia.
They are treating it with antibiotics, and he is responding well.
When the pneumonia passes, they will again consider surgery.
