What I remember most about that the night of May 16 was the huge crowd (we were in it) in front of City Hall that filled the whole street. It was a blast of happiness and was quite incredible.
On the way home from today's celebration we chatted with a nice women (who was opposite-sex married) and her child; she was gushing about how wonderful it was and the reality of this situation that makes so much sense. She said "have you every heard an opponent give a good reason?"
And next Wednesday, I go to the first meeting of the Cambridge GLBT commission to which I was appointed by the City Manager and am interim co-chair.
Ours was on August 4th: see rsc's post.
