The cold is a real economic lifesaver up here. The lakes are finally freezing up at record late dates, and allowing for winter activities to progress.
This upcoming weekend is the U.S. National Pond Hockey championships on Lake Nokomis a few blocks from my house. As recently as last week there were questions on whether or not there would be enough ice. With these temps the lake is making about an inch of ice a day and the tournament will proceed as scheduled.
