At 109 years old, the Boston Marathon is the oldest and most well-known North American marathon. What amazes me, is how it matter-of-factly swings through streets in my little neighborhood. People crowd the sidelines along the entire route to cheer the runners on. Every time a runner passed the crowd would applause and goad the runners on by saying things like "Yeah! you can do it! Good job!" This picture was taken a mile before the finish line.
