I'll be honest with you...you're a married guy from Alabama and never been to Boston. If you don't like history, walking all day, get crammed into an old creaky train, trip over bricks and encounter a lot of rude people who aren't really interested in conversations then you'll hate Boston. Having said that-
-Boston duck tour
-Fenway Park tour
-walk around Harvard Square and Harvard Yard
-walk the Freedom trail and go to all its big destinations (Park Street Church, Old North Church, Bunker Hill monument, State House, Old State House, Granary Burial Grounds)
-hit up the classic bars on Canal Street (Sullivan's Tap, the Fours- this actually was voted America's best sports bar in Sports Illustrated maybe 2005 or 2006?- World's Greatest Sports Bar, Hurricane O'Reillys)
-check out Red's statue on Fanueil Hall (pronounced as Fannel, not Fan-yoo-ell)
-don't say "yeah baby we're in beantown!" "yeah baby, we're in Bah-ston!" is more appropriate
-picket for a Bill Russell statue in front of the Garden.
Hope you have a good time!
