Calling all Bostonians

It's just gorgeous weather here outside Boston. The blossoms and flowers look almost psychedelically colorful and ripe. It's sensory overload, practically.

May 14th is Lilac Sunday at the Arnold Arboretum in Jamaica Plain. I've never been before, and am expecting a mad scene if we do make the hike out there. It's the one day per year they let people picnic on the grounds, a big ol' Boston tradition. Since I'm fond of my adopted city (technically I'm a bit west of Boston, out in suburbia), and I'm not sure whether we'll still be here another year from now, I'm wondering what the "typical", "must-do" Boston experiences are. Cape Cod (check), Fenway Park (can't afford it), swan boats, 4th of July fireworks on the Esplanade (check, but I should go back), yadda yadda. Let me make it clear that I'm no tourist. But I want to be able to say I took a big, juicy bite out of the...Bostonian equivalent of the Big Apple. Oh, as for lobster, I can take it or leave it.
