I posted the booms in Columbia County, Georgia on "the facebook" to see if any family or friends heard or experienced them - have heard nothing back yet, although, according to the news - it was on the road my family lives on.

Maybe you're correct - my family are all Christians and thus far no one has spoken that they heard it.

I wrote a lot of articles about blue beam 5 or 6 years ago, so I'm familiar with the concept.
