Dan was a friend of mine in college--met him in 1974 when he was coming back from the Chargers to finish up his degree.  One of the most real human beings I have ever known.  As a dad who also lost as son, I understand the never ending sense of loss but the also the joy of recalling who he was and what he brought to our family.  God bless you Dan and family and the work you are doing to help eradicate cancer.
