I absolutely remember many of our online interactions, both public and private. Quite obviously, no objective blame is yours to shoulder - his health deteriorated unpredictably rapidly, and that is tragically a part of life. Time, sooner or later, gets to us all. To some extent, that's one of the reasons we appreciate this very hobby as much as we do.... Evidently, Casey was a strong willed person who spent his last weeks the way he deliberately intended to. My wholehearted gratitude for you reaching out to all of us here with this delicate and touching story! Be well, be guilt-free, and feel free to email anytime you wish! All the best to you and yours.
