When I see a photo opportunity, I jump at it. I had just finished a bike ride along Waterfront Park and Eastbank Esplanade when I saw a new MAX coming, threw my bike down, got on my knees and snapped it as fast as I could. It turned out pretty good and remains one of my favorites.
Oh, and in case you wonder what my criteria for my picture of the day is
1. It's one I took
2. It'd look good as a wallpaper on my phone
3. Never deliberate before looking on which one you want. Make it completely random.
