It's not just new attractions that make Buffalo worth visiting. The Albright-Knox Art Gallery (1285 Elmwood Ave., albrightknox.org) opened in 1862 as the nation's first modern-art museum. On a walk through the bright, open galleries, I saw a mind-blowing constellation of work — Picasso, Gauguin, Kahlo — without the mobs of Manhattan museums. The landmark Frank Lloyd Wright's Martin House Complex (125 Jewett Pkwy., darwinmartinhouse.org), built a century ago in leafy Parkside, stands as a stunning example of the architect's work. It's getting restored to its original patina after years of neglect.
