People view the Cherry Blossom trees near the Tidal Basin in Washington, in this file image from March 29, 2011. Above-average temperatures have brought February, 2012 blooms to Washington, but organizers of the centennial National Cherry Blossom Festival see the springlike winter as no threat to their celebration. The festival draws thousands of visitors each year to the capital's Tidal Basin to enjoy the pink and white blossoms. This year's celebration carries a special cachet since it marks the 100th anniversary of Japan's gift of cherry trees as a sign of friendship with the United States.
