My sister, Alissa, has a daughter at Babson and a son working in Waltham. She came to visit them for the weekend but I probably got to spend the most time with her. We drove into Boston where we did a fair bit of walking along the Rose Kennedy Greenway, along the harbor, and around the Faneuil Hall  Marketplace where we had dinner. Between the buskers, kids playing in the fountains, and seals of the Aquarium we were treated to a wide array of entertainment.
