Nippy day, crisp wind, lots of sunshine, and early leafing is there for the looking. The leaves are tiny, so too the branch flowers, but a pause on a park pathway reveals the fresh green and the baby blooms. Within a week or two, leaves will be abundant cloaking the branches. But now their miniature beings resemble tiny birds, wings aloft in graceful flight. For some, early leafing is the prettiest of all spring sights.
