          A Tour of the Upper Watershed
          Participants on this tour boarded a yellow school bus at the Cambridge 
          Water Department, and were driven to Waltham. There we visited a redevelopment 
          project at the former Polaroid site at 1265 Main Street, near Route 
          128. Dave Kaplan, Cambridge Watershed Supervisor (left photo) described 
          to us how the water department and the developers are working together 
          to prevent storm water runoff and protect the nearby Cambridge reservoir.
