Success

Our outdoor dance floor worked perfectly, and the weather cooperated. No rain, seasonably comfortable. Without lights, our dance party was from 4 to 6 PM, and lightly attended. Maybe in June, more people will be as inspired as I was by the beauty of the outdoor space. I heard dancing under the stars at Seaport was very nice, too, though it must have gotten quite chilly at night.
Forgot to take a picture.
