Who says Minnesotans don't have big dreams? Back in the 1980s, then Gov. Rudy Perpich thought our great state should host the Olympics. Plans were made to build a huge rink that could host major events. But wouldn't our lack of mountains always keep us out of the running? Well, maybe we could use it for summer events.... Anyway, the upshot is we now have the largest outdoor refrigerated rink in North America. The cumbersomely named Guidant John Rose Minnesota Oval, which opened in 1993, is 110,000 square feet of refrigerated ice. From November through March it offers outdoor skating even when temps are above freezing. It has hosted World Cup speed skating, bandy championships, and outdoor practices for the Minnesota Wild. From May to September, it's converted into a skate park, one of the largest in the Midwest. The Roseville Skating Center, of which the oval is part, also includes an indoor arena with seating for 2,000 people, so ice is available there year-round.
