But this new troop was unique. It belonged to girls who did not know where they belonged. It wouldn’t make sense to use the numbers normally applied to troops in any of the five boroughs. Given that its members had no fixed addresses, wasn’t this troop of girls, no matter where it was located, really like a floating borough in its own right? Or even a shadow borough, because the rest of society was ignorant of or didn’t want to acknowledge its residents? At some point Girl Scout staff realized that the 6000s, designated years earlier for specialized troops, like those for girls with special needs, were no longer used. And so, the Girl Scouts of Greater New York settled on the name Troop 6000.
