Nobody is thinking about frozen lakes this time of year, but we will be soon enough. We’ve just had two of the harshest and coldest winters in decades.
Two years ago, at one point 93 percent of the Great Lakes’ surface was covered with ice.
Last year was almost as bad. The lakes are, as U.S. Sen. Gary Peters reminded me this week, a major American commercial highway, with freighters carrying billions of dollars worth of iron ore and other materials moving across their many hundreds of miles.
