yes, I'm aware... I was a messenger and cab driver in Boston.
Symphony could mean the part of the South End right behind the Colonnade, or more likely, it means the Fens... and Fens + Bianchi Pista sounds like a college student playing around with a fixed gear in an ungentle way (a theory that would seem to be supported by the stripped lockring). Even if it's not a college student, fixed gear plus Fens still sounds like they may have taken a beating.
