I was walking the dog and it ran in the woods i went to recover the dog and noticed something at the corner of my eye and when i raised up from recovering the dog. i started to turn to look when this grey 4 foot tall made 2 loud screams i've never heard before! i got a small glimpse and took off running to the house. it happened around 8am the hairs on the back of my kneck and body stood straight up, might be out of fear. i heard low beeping noises for a couple days after having this encounter and had a transformer to blow up about a mile away if at that from where i seen it. no lightning storms where around.
