All week long, Major League Baseball teams around the country have been honoring the Boston Marathon bombing victims and the city itself. One way they've done so is by playing 'Sweet Caroline', a Neil Diamond hit that became an unofficial Boston Red Sox anthem during the 7th-inning stretch.

The idea is spreading through word of mouth and via a Facebook page that already has 334 members and is growing by the hour. Members are sharing their own plans, as well as places to buy red socks that are conducive to distance running. Some participants plan to wear socks with the Red Sox' logo, while others are going with a plain sock. The key here is the color.
