After a hot, gusty, cloudy day, by evening the wind had died down, the clouds had dispersed, and the air was calm and almost sultry as a big full round orange moon rose and shimmered behind the dark outlines of the trees. Two bats swooped low over the grass and all around us as we walked up to the top of the driveway in deep twilight to see the moon and watch the bats appear and disappear and the last light fade from the sky. It felt like a preview of summer.
