I and my boy were hot tubing in the back yard. I was looking at Orion and notice a movement of what at first looked like a whisp of a cloud. Looking directly at it I new it was not natural and had a solid triangular body to it. I told my son to look at it, that it was a UFO. We watched it until the roof blocked the view. I then jumped out and ran in the house to tell another child to come see the ufo. we ran out the front and then I retreated to the house as I was naked and dripping wet from the hot tub. He later came to the back and said he had seen it too. (I had seen a simmilar craft about ten years ago 50 miles to the north. It was traveling north to south.)
