So Bruce, I take it you once lived or worked in or near Watertown? I lived in Natick, Needham, Newton, Wellesley, Brookline at various times. Watertown is cool. Waltham is too, but it's becoming very gentrified.
Are you a member of ASCE? I myself have done some industrial archeology and written papers on some major CE/chemical engineering projects.
Have a good weekend.
