David -
Both you and your father are the rare kinds of people I'm proud to say I know - even though we only had a forum "relationship" - some folks' strong character just shines through their words and mannerisms.
I'm very glad your Dad was around to see you graduate lawn school summa cum laude - I'm certain he was very proud to share that moment with you - and will be with you, gently guiding and encouraging you, the rest of your life.
My family will have you in our thoughts.
TJ
