Jocko, another year has passed. I have had several people ask me if I remember what took place today, and I responded with " We lost a good friend 11 years ago today". I am not amazed that people still think of you, and still talk about all of the memories they have of you. Just know that you are still on everyone's mind, and your are missed by many.
