There is a new update at the DAVID link at right.

BREAKING NEWS - This just in :-) David's cardiologist just called and wants to move the surgery date up to March 11. David's not home, so I'm not sure if we'll be making this switch. We've been so eager for this to hurry up and happen, but I had my mind wrapped around March 25, so I need to readjust my expectations and timing. I think this will be a really good thing if it can work. Then David's surgery will be done before Easter break, and he'll be able to do part of his recovery over a vacation time - and the boys will be home with him then. David or I will post when we hear more.
