125 follows the same habits as 246 in that they acquire a lot of high schools which are no longer with the team today although the team itself survives (the orange 125 is next to the orange 246 on the picture). The purple 125s relate to one of these schools: Brookline High School & Catholic Memorial & Milton Academy & Newton Country Day School & The Winsor School.
Boston Latin School, the original carrier of the team, is in it’s 10th participatory season. According to the records from the archived FIRST team listings on archive.org, Winthrop has never been mentioned on the official listings. So, I will change that orange square to red, thanks for pointing that out.
A dormant team is defined as one that participated but did not participate in the current year. Team 690, Western Massachusetts Electric Company & Smith Vocational and Agricultural High School from Northampton, competed in the 2002 season but there has been no listing of anything similar to that since.
