A sure sign of springtime in Washington D.C. is when the cherry blossom trees come into full bloom along the Tidal Basin.
A sea of pink stretches from national monument to national monument. The 3,000 cherry trees were a gift from Japan in 1912 as a symbol of friendship between the two nations.
Now each year the blooming of the trees is marked with a Cherry Blossom Festival. The celebration grew from humble beginnings to a great spring festival drawing thousands of visitors from around the world.
