On Saturday, Sari and I made our annual pilgrimage to Kimballs for lobster roll.  Kimball Farm, which started as an ice-cream stand in Westford, Massachusetts, has ballooned into a huge enterprise over the years and there was a big crowd lined up in front of us when we arrived.  Undaunted, we traced our way to the back of the line and hoped it would move fast.  It did not.
