The Great American Solar Eclipse is almost here, but one expert says it may result in a “zombie apocalypse” of sorts. This once in a lifetime event will take place from Oregon to South Carolina on Aug. 21, and it will likely draw huge crowds to gather along the 70-mile-wide band of totality, and that could lead to some potential problems.

Angela Speck, a researcher at the University of Missouri, used the term “zombie apocalypse” in an interview with Space dot com, saying that since most Americans live within a day’s drive of the eclipse, there could be a huge amount of people traveling by air, train, and car to a small zone, and people going about their day may find huge amounts of people simply standing around and staring.

“There will hopefully be less bloodshed, but zombies don’t need regular food, or sleep, or toilets,” Speck joked according to the report.
