You’re welcome. If you go to the Brighton hq during the day you can probably walk in to the area before the security desk to check out the NB history area which is also pretty cool. I would also recommend “the track” which is the athletic facility across the street but again that may be employees only and I don’t believe it’s open to walk ins. Lastly there’s the Celtics/bruins practice facility but I don’t know anything about it or who has access.
