If it is not sinkholes its booms.. A loud boom (some report more than one) was heard in Arizona.. Law enforcement has no answers.. Media has no comments from officials saying they know where it was from or what it was..
Just more examples of these noises happening all throughout the United States..
Incidentally, Linda Howe was on Coast to Coast AM last night with someone who believes he has answers to the nationwide boom question: Weapons testing.
No comment from me on the veracity of that belief.. But I know the noises are all over–even close to Horror Report home base as I reported a few days ago, when a loud boom shook several neighborhoods on Northern Schuylkill County, PA..
