In the winter, northern regions with lots of water features become vast fields of ice. Because the shortest distance between two points is a straight line, you might be tempted to cross that frozen lake rather than go around it. That’s fine if the ice is thick; but, if it’s not, there’s a risk of falling through the ice. If so, you’ll be in extremely cold water (and extremely big trouble).
