Watch: Red Sox fans sing 'Sweet Caroline' outside Fenway Park

Red Sox fans celebrated Truck Day by singing none other than "Sweet Caroline."

Thursday was Truck Day at Fenway Park, the day the team's equipment crew packs up everything to send down to Florida for spring training. 

And even if the stadium is currently covered in three feet of snow, that didn't stop Red Sox fans from trying to make it feel like spring already.

As is custom for gatherings of Boston fans, Neil Diamond's "Sweet Caroline" inevitably ended up playing, so the fans on hand broke out into an impromptu rendition.
