Mike and Shirley ran a successful painting business for over 50 years. He was meticulous, worked many hours and at one point even employed a crew of 15 workers. He was an avid outdoorsman and loved to be at the cottage enjoying fishing, woodcutting, tinkering with mechanics, snowmobiling and of course, hunting.
