They note at the end this is about the huge tornado outbreak of April 3, 1974, which my sister & I spent in the bathtub at my grandparent's home, who didn't have a basement either.
Love the part where the people are calling EMS to *complain* that the area's sirens just keep blaring & need to be turned off.
'Cause they're annoying people.
