I call that Spring!

A kite, a sky, and a good firm breeze,
And acres of ground away from trees,
And one hundred yards of clean, strong string --
O boy, O boy! I call that Spring!
--Mark Sawyer

There wasn't exactly a good firm breeze, but children in the park had fun getting their kites airborne. I love the simplicity of the red kite.
