Celebrate Japanese culture and admire the stunning cherry blossoms at Washington D.C.'s annual National Cherry Blossom Festival.  The city turns pink and white as the blossoms come into full bloom, creating a pretty image to kick off spring.  Wear your best pink formal attire to the Pink Tie Dinner Party, fill the sky with color during the Blossom Kite event, and listen to live music along the Anacostia River during Petalpalooza, an outdoor street festival with food, entertainment, and fun activities.  Admission is free and more information can be found on the official website.
