We were staying at my wife's mom and dad's place. We were staying in our fifth wheel travel trailer. At about 9:20 I took our dog out to use the restroom. The night was clear and warm I was looking at the mountain range that is not very far from where we were staying. After the dog finished his business I picked him up and was walking back to the trailer. There was 3 very very bright flashes of light. I'm taking like they were as bright as welding flashes. I was walking to the west I turned my head over my left shoulder and seen a ship that was huge just sitting there. It was triangular shape with lights running down the middle of it. The lights were white and I could see the shape very clearly. I stood there for a bit just looking at it. All of a sudden I took off running towards the trailer I was probably about 15 feet from the door I jerked the door opened and told my wife come here and look at this. She was getting up when I looked back up over my right shoulder and it was gone. I stepped away from the trailer and started looking for it.I looked all over and it was not there.I never heard a noise or anything. I told my wife what I saw.I still don't know how anything that big could have disappeared that fast. I didn't sleep very well that night. I asked my father in law if they had ever seen anything weird before and he surprised me and said yes. I told him what I saw and he said they have never seen anything like that but they had seen other things. For some reason he still will not talk about what they have seen.
