As we approached the Jefferson Memorial, the Cherry Blossom Festival stage came to life.

Based on the media presence, this was to be a big event.

Then we noticed Yoko Ono, waiting to go on.

She invited people to write wishes and tie them to the branches of "wish trees," forming the "blossoms" of the trees. Six trees are near the Jefferson Memorial, and four more at various spots around the city. She has already collected more than 100,000 wishes from other wish trees around the world.
