When a bunch of people head to one place, they all have to turn around and come back eventually. Such is the case with today's total solar eclipse, and it could lead to one of the biggest movements of people ever,
UPI reports that the rare event could lead to one of the largest mass migrations of all time, as a conservative estimate of two to seven million people may travel to get a proper view of the eclipse.
All those people are in a space 70 miles wide and 2,800 miles long, the so-called path of totality, and have to come back.
Experts have compared the return to 6 Denver Broncos games letting out at once.
