WENDEL CLARK says he made the move from hockey superstar to rink rat "a little too easily." But then, the retired Toronto Maple Leaf player, known for his scrappy hockey style and relentless energy, owns the rink in question. He has finessed the Canadian winter tradition of making a skating rink in the yard. "It is still a rink in our big backyard," he says of the enclosed ice surface 150 yards from their house. Clark, his wife, Denise, and their three children enjoy the country lifestyle on 40 acres in King County, north of Toronto. "The idea that kids could walk to the rink was something that I grew up with," says Clark, whose family farms near Kelvington, Saskatchewan. "We all took it for granted. A rink was a fun place to be, no pressure. [It was] our recreation room. We've taken that one step further at our home."
