Description: I took 99 North coming from Turlock to Modesto. I had been out doing karaoke. After exiting the freeway I turned right off of a one way street (G St) to 13th Street in downtown Modesto. It was either a Friday or Saturday night. Immediately after turning onto 13th, the sky changed! The night sky disappeared! It was covered by a black circular object. I immediately stopped my 89 Ford Escort in the middle of the road and turned it off. (I had my sister-in-law with me.) We stared and opened our doors. I stood up with one foot still in my car. She had both feet out of the car standing outside the car, at the window. It was like it was watching u,s BUT we could see no windows at all. It exceeded the width of the wide street AND the houses across the street from each other. The only light I kind of remember was from a streetlight or a house porch light. This is how I knew it was mostly flat and rounded. It was about 10 feet in front of us, and 25 feet above us. It was HUGE. It seemed to be resting on the trees. It was hovering. My sister-in-law & I looked at each other a couple of times. She was frightened. I felt no fear whatsoever. I remember there was no sound at all. It was a huge circular object and it made not one decibel of SOUND! And then suddenly it was gone, in a split second, no trace of it’s direction. Knowing my sister-in-law was frightened, I did not want to scare her anymore, so I told her that since our local airport was just a mile or so away that it was probably an xperimental aircraft. But I KNEW humans are not capable of making such an aircraft, that big, that silent, that fast. I do not recall seeing any lights emitting from it, nor windows. But I did get that feeling of being stared at. But how could “it” stare through this metal looking material, appearing smooth in texture, and not be at all transparent? And looking from the only light I recall, I do not remember even seeing a seam anywhere. It was very smooth. It seriously did a Houdini and disappeared. It moved too fast to be humanly built. It was far too big to actually hover! It’s been so long ago, that it wasn’t until a few years ago, I recalled it and still think about it sometimes. I cannot remember it all as clearly as I wish I could. Just last year I reminded my sister-in-law who recalls nothing at all. Being as scared as she was, I cannot comprehend how she could have forgotten!
