August

Italian-American Feasts, North End. These weekend street fairs begin in July and end in late August with the two biggest: the Fisherman's Feast and the Feast of St. Anthony. The sublime (fresh seafood prepared while you wait, live music, dancing in the street) mingles with the ridiculous (carnival games, tacky T-shirts, fried-dough stands) to leave a lasting impression of fun and indigestion. Visit www.fishermansfeast.com or www.saintanthonysfeast.com for a preview. Weekends throughout August.

August Moon Festival, Chinatown. A celebration of the harvest and the coming of autumn, the festival includes dragon and lion dances during the parade through the crowded streets, and demonstrations of crafts and martial arts. It's also an excuse to stuff yourself with tasty mooncakes. Mid-August.

Buy tickets (tel. 617/695-6955; www.bostonballet.org) as soon as you plan your trip, ask whether your hotel offers a Nutcracker package, or cross your fingers and check when you arrive.

Boston Tea Party Reenactment, Old South Meeting House and Tea Party Ship and Museum, Congress Street Bridge. Chafing under British rule, American colonists rose up on December 16, 1773, to strike a blow where it would cause real pain -- in the pocketbook.
