Mark and I were friends and housemates during college years at IUP. He was in my wedding. We hitchhiked out West together, and visited a relative in San Francisco -- we laughed about that journey just a month ago. I visited him a few times in New York years ago, and had chatted on the phone several times in recent months. These are good memories. I will miss him deeply. His convictions were strong, despite the hardships; the illness didn't distract him from his faith.
