I’ve never taken the groundhog’s shadow seriously, especially when late March gave us cold rain and wind with temperatures that were hovering close to the freezing mark. At the same time, there are signs of optimism in the cherry blossoms blooming next to the New York State Pavilion in Flushing Meadows, a long-neglected World’s Fair structure that is undergoing a restoration: better weather, reopened museums, and restored landmarks. If you’re home for Pesach or visiting family members in the suburbs, there’s plenty to see around the city and its vicinity.
