Many decades ago, I visited a college alum friend of mine who lived in Wisconsin. He took me ice boating which was a scary experience for me. The ice boat was a triangle made from three 2 by 4 pieces of lumber with a sail & could go faster than the wind by not going in the exact direction of the wind. The view of the ice from less than a foot away made the speed seem faster than it was. Do the Great Lakes ever freeze over? At the time, I assumed we were on one of them, but on thinking about it years later, I wonder if we were on some smaller lake that seemed like a Great lake to me. In Eastern Pennsylvania where I live there is no lake which could be confused with one of the Great Lakes, but in Wisconsin there might be.
