David Colburn COOK- It’s a long-held and widely accepted rule that umpires and officials are supposed to be impartial, no matter the sport, no matter the ages of the athletes. But it’s difficult to imagine anyone faulting Bill Peterson, of Cook, for an inadvertent slip last week. After all, after four decades of officiating football, basketball, baseball and softball, he’s earned a little grace. Over the years, Peterson has refereed games involving all his grandchildren, but umpiring a junior varsity softball game at North Woods School last Thursday, May 6, gave Peterson an opportunity to take that experience to a new level. Great-granddaughters Hailie and Emma Peterson, 14 and 13, respectively, were in the lineup for Cherry, the Grizzlies’ opponent, and Peterson was behind the plate.
