Memorial Drive in Cambridge, MA, facing east with no cars on it because it is Sunday afternoon. There's a long line of cargo bikes parked in one lane, with people standing in and around them. JFK park is on the right, with a bunch of kids playing with stuff provided for their amusement (a giant tetris yty, some bubbles). I got lucky and not too many faces are visible, I think the ones that are, were associated with the event. I took the photo standing on the deck of my cargo bike, as one does.
