Report 69564: Witnesses hear multiple wood knocks while night fishing near Mt. Union

One night me and my friends went catfishing in a local spot near my town. We had set up at about 8:30 p.m. and we're having a good time. At about 9:00 p.m. we had our first bite and ended up being a 15 minute fight to end up being a turtle.  Shortly after at approximately 9:30 p.m. we heard what sounded like our first wood knock.  Personally I didn't believe or didn't want to believe what I had just heard. But within minutes we all heard the 2nd knock and were all speechless in what we had just heard. After talking about it for a couple minutes we heard another but this time it came from the other side of the river, speechless yet again we all just looked at each other and within seconds we heard another but this time it was right being us and close. That's when we knew we had to leave.  As we were packing our fishing poles in the car we heard 4 loud aggressive knocks within 30 yards of were we parked. We immediately showed the poles in the car and left.  After getting several miles down the road we stopped and said let's go back and try and get it on video because know one would believe us. So that's what we did and we got 3 knocks on video.
