When: New Year's Day.
Where: English Bay, Vancouver, British Columbia, Canada.
What: Since 1920, thousands of brave (or foolhardy) souls have been diving into the near-freezing Canadian waters to kick off the New Year. Think of it as photographing on the beach, except hundreds of people are charging into and out of the water every few minutes. Tip: With so many people and a relatively flat surface, experiment with holding the camera high and shooting wide for in-the-moment action shots. For info: www.vancouverparks.ca; 604-257-8400.
