NEEDHAM, Mass. — Erika Tarantal heads to the river: the Kennebec River and the town of Bath, Maine to be exact. There, she hops the city trolley to tour the retro, yet revitalizing, downtown. Then, she heads to the water for a riverboat tour and a look at Bath’s shipbuilding history. Summer vacay isn’t complete without a little indulgence (read: food!), but since Erika is on assignment, she’s doing the cooking! On the menu: Native American cuisine.
