One of the great things about living in Ottawa is the winters. We have the largest outdoor skating rink in the world, The Rideau Canal. It used to be branded as the longest, but Winnepeg built a longer one. Fortunately because of the width, we managed to retain the title of the largest.
When skating on the canal make sure you stop for a treat from one of the booths set up. Beavertails are a particular local favorite.
