ng, being in the UP among nature in all seasons was his heart and spirit rejuvenating joy. Mark's love of the UP was shared by his wife Catherine. She was the love of his life and he was the love of her life. He was a wonderful husband. Mark and Catherine shared many passions but particularly that of being the best possible parents to their two wonderful boys. Mark was the best dad ever. His sons were the center of his life and he made all efforts to be the kind of father he knew they deserved. Although a grown man he was still a child at heart when it came to spending time with his sons and his sons friends. He loved showing them the wonders of his many hobbies.
