Cardboard frames for solar eclipse glasses are stacked in the American Paper Optics factory in Bartlett, Tenn., on Wednesday, June 21, 2017. The company is one of many businesses — hotels, campgrounds and stores — taking advantage of the total solar eclipse — when the moon passes between Earth and the sun. The moon’s shadow will fall in a diagonal ribbon across the U.S., from Oregon to South Carolina. (AP Photo/Adrian Sainz)
