This from the Red Sox:
The Boston Red Sox will once again open Fenway Park to the public for a free, day-long open house on Wednesday, April 17.
From 9 a.m. to 5 p.m., fans can enter through all gates free of charge to view historical artifacts, memorabilia, and displays throughout the ballpark. The open house allows families to walk around Fenway Park at their own pace, discover behind-the scenes locations, and to learn more about Fenway Park’s history.
Fans will have an opportunity to walk the warning track, peek inside the Green Monster scoreboard, and visit other spaces within the ballpark not normally accessible to the public. Red Sox alumni will sign autographs throughout the day.
Fenway Park concession stands will be open, and the event will take place rain or shine.
The Red Sox held the first Open House as part of their 100th Anniversary celebration of Fenway Park in 2012, and nearly 54,000 people attended throughout the day. As it was last year, the event takes place during school vacation week.
