Hockey fans, assemble! The 10th anniversary of the Bridgestone NHL Winter Classic will be big, especially for Gothamites. The match is between two Empire State teams, the Buffalo Sabres and the New York Rangers. What makes this game so special is that it’s being played outdoors: Citi Field is bringing in an ice truck to create a temporary rink. Before the stick smackdown, there’s a free pregame festival for fans with giveaways, food and drinks at Lot F in Citi Field’s parking lot (9am to 1pm).
