I am planning an online celebration of my big brother, David, a humorist, excellent writer, folksinger and family man who died on Friday after open heart surgery. He was only 43. My family and I raced up Highway 50 toward Carson City to be by his side, but it was already too late by the time we got there. On Thursday, dozens of his friends and colleagues will be joining my family to celebrate the life of David. Many of you who check this blog on a regular basis already know about his hilarious YouTube and MySpace videos — and the stunning final video that he shot just before his surgery. All of us miss him terribly. There is so much more to say about him, but for now, I just want to send my prayers for David and good wishes to his family.
