In 1968 his family moved to Gillette, Wyoming for the oil fields. In 1969 his mother married Delbert Blake. Growing up Mike enjoyed wrestling, fishing, and having a fun time. He was most known for his ornery and comical personality. He worked most of his life in the Oil Fields. Mike met Crystal Haukaas and had Trevor in 1995 and Melissa in 1998. He had lifelong friends who will all remember watching football games or NASCAR races together. Both friends and family will remember him as a fun time to be around. In 2018 he became a grandfather, and nothing made him prouder. Mike is survived by his daughter, Melissa (Kody) O’Brien; brothers, Larry (Dianne) Dayhoff; Randy (Carol) Dayhoff; Jim (Sharron) O’Brien; and Mark (Deborah) Blake; sister, Vonda (Dan) Jordan; grandson, Gunner Raleigh, and numerous nieces and nephews.
