Headed out to Boston/Salem/Topsfield next week.

Will wander around where my Puritan ancestors first set up shop in
America. (ggggggg...Great Grandpa Zaccheus' house is on the national
register of historic places in Topsfield, as is another
gggggggg....grandfather's barn)

Going to visit Old Ironsides (she's moored in Boston, right?)

Since I seldom get back to the right hand side of the country, are
there any other "must sees" during a few days in Boston?
