Ventura Alien

While up at the cross in Ventura, CA up on the hill overlooking the city, I was there on a night run and a UFO was parked in the parking lot. I was like, dumbfounded, because if you drive or run up the road, you know it is a very isolated area. Anyways, There was a sort of fog that was being released from the bottom of the craft. It was dead silent which was weird because when I had been jogging, I could hear all kinds of noises from trees, animals, etc. Then I heard a sort of muffled high pitch squeel. As if you had a nail in a piece of wood and you were moving it on cement with your foot. I heard some foot steps and booked it back down the hill. The next day I went back and nothing was there, but a small little piece of metal that was shaped very oddly.
