Oh my goodness. Remember when the monument was on the rotary out front of the Boys Club. There was a half circle of stone, with a seat all the way along the half circle: open side toward the Auditorium. (They moved it a little ways away later, out behind the Boys Club, I think, after they changed the roads - after I moved away from Worcester).
Two people could sit at opposite ends of that half circle - and even with all the noise of the traffic driving around the rotary, the two of us could sit there at opposite ends of that half circle - and talk at a NORMAL level - not shouting or even raising our voices ... and we could hear each other all the way across that circle.
GO there and check it out. Something about the acoustics of the stone half circle carried the sound all the way around it, like a little amplifier.
