I have walked my dog in the same place for 2 years plus. There is a 20 acre field next to where I walk him , I Felt a wooping noise ( woop woop woop ) You could feel it in your body. We have trucks on the interstate and I know that sound and it was not that !The dog paid no attention to the sound at first, but after we were back on our property he looked toward the north and I looked and saw sparks from the field, the dog barked over and over again , and then stopped. Seeing the sparks between the two houses and the field was strange . It was the weirdest feeling I have had , and I am an avid hunter, and I am always in the woods and have never heard or saw anything like this ever! The sound went right through you. I did not see a craft or any kind of lift off ,Just sparks, but I know there was something there! I brought the dog home and told my mother , and then went back to the area with a 2 million candle power light and saw nothing. If my neighbors saw me the must think I am crazy. I am a 49 year old male and It scared me !!!!!
