From a Braves press release:
Throughout the 2016 season, the Atlanta Braves will be celebrating the memories and moments that made the last two decades at Turner Field such a storied part of Braves history. The Final Season at Turner Field will be commemorated with a special jersey patch, pregame ceremonies, limited-edition gate giveaways and more. …
At the heart of the Final Season will be the stories and memories of the fans, season ticket holders, players, coaches, staff and more that made Turner Field their home over the last twenty years. The Braves want to hear every Turner Field story and will collect and celebrate these moments – no matter how big or small – in stadium, on the website and in other ways this season.
