It is amazing what you can learn in a park in a subzero winter day. It's like life gives you a snapshot of geology in the freezing and thawing of one day. Lessons of physics, and ecology and forces and temperature all abound. You can be a hunter, a polar bear, a penguin or a tracker. All with a little much needed vitamin D!
