Best Alfresco Dance Party

Every Sunday, around 10 or 11 in the morning, a few dozen terpsichoreans gather in the park's concourse, slip some Basie into a boombox, take to the stage, and dance. It's all very casual and unofficial, and the dancing reflects it: The moves aren't rigidly flashy, like you see in ballroom dance competitions, but free and easygoing with a lazy sort of gracefulness, like an old Hoagy Carmichael tune. The effect is of a morning-after jam session, and everyone has a good time, particularly the spectators on the park benches sipping their coffee in the sunshine.
