The Bruins are heading back outdoors, so why not relive some moments from Boston's previous Winter Classic games?
The B's are in Lake Tahoe to take on the Philadelphia Flyers, a team they have had great success against this season.
Boston is 4-0-0 against Philly in 2021 and look to continue that streak. Meanwhile, the Flyers hope to bounce back after a loss to the New York Rangers.
Before the puck drops Sunday at a 2 p.m. ET, let's take a look at some moments from the Bruins' three Winter Classic appearances.

Bruins and Canadiens entrances at Gillette Stadium were awesome
Sean Kuraly's go-ahead goal against the Blackhawks (Starts at 2:55)
Of course, you can't forget a packed Fenway Park singing "Sweet Caroline" led by Dennis Leary and Lenny Clarke.
Ah, memories.
