Was hunting in a club outside Vernon in Lamar County. Had several gas wells on the property. The last gas well on the property was in what is best described as an "odd" area. Everyone that hunted it always commented how you just felt weird when going to hunt that area of the club. My wife and I went one afternoon to hunt there. Had to walk down this fairly steep hill to get to the swampy bottom area. There was a fire break you could walk for probably 800 yards on the left and a nice oak flat just off a pine thicket to the right. Great area. Walking down the hill we keep hearing this buzzing sound kind of like a humming bird or a large bee fluttering around. You could hear it flying in a large circle through the woods and across the trail down below us. It sounds weird, but you could watch it's path circling just by hearing it. Louder, then quieter as it made it's circle, but you couldn't see it. When we got down closer, just by where it was flying, we both got close enough to where we could feel the buzz in our chest, but never once saw what it was. We walked down into the circle and could feel it circling and feel the buzz on our chest and backs, like it was pulsating. Once it was on it's way away from us, we walked on down, but could still hear the buzzing and circling down in the oak flat about 60 yards away. A doe came down the hill on that same trail a little before 4, but when she got to the buzzing circling sound, she about turned inside out getting out of there. Never blew or snorted, just jumped up a couple feet, stumbled and took off like a rocket. The sound started dying down and finally quit. We walked out at dark and didn't hear it on the way out.
