The moon passed in front of the sun and turned day to night. Hasn't happened since 1979 (which, incidentally, is also the name of an important Smashing Pumpkins song). 

We hope you took a moment to enjoy this fantastic celestial event. Sam and his pop drove to John Day, Oregon right in the path of totality. He wore his Night Bo Shorts to honor the miracle of day-turning-to-night.
