Ron's surgery was yesterday. He posted this on Facebook a few minutes ago. "They did a double bypass and new heart valve. Everything went smooth. I'll post more when I feel up to it. Thanks for all your prayers and good thoughts."

Latest update: "I've been cut up, have chronic back pain, COPD and haven't slept more than an hour or two in the past four days. but the operation worked better than I could have imagined. They gave me a transfusion tonight and I feel more like 16 than 61."
