Interesting audio captured. Here is the information I was given: “Audio original below on a google drive. Can you open it.
This was recorded 2:30 am by fisherman on his cell phone, on July 15, 2018. The recorder, Joe, would discuss it with you if you wish. This was on the Potomac River in West Virginia. He said the yells were coming from about 200 yards away and yelled about 3 times before he started recording.”
