Numerous residents of a Spokane, Washington suburb reported hearing unsettling trumpet sounds overnight on December 14. Listen to a recording of the noise below. Non-believers suggest that it may have been the sound of many snowplows scraping the concrete roads or train rails creaking in the cold. One news outlet's "science expert" commented that "temperature does affect the speed of sound, which can make certain things sounds different than what we are used to hearing."
Of course, we all know the truth: It is the seven trumpets as described in the Book of Revelation. The apocalypse is nigh, and it's starting in Spokane.
