Hi all, I am heading to Boston for a 4 day conference thus upcoming Wednesday. Will have some time in the late afternoon and evening to do sightseeing (maybe some during the day). I'm staying at the Copley Marriott and my conference is at the Sheraton (John Hynes Memorial Center). What do I need to do and see to experience Boston? I do already know about Newbury, Prudential & Copley Place for shopping!
