2:30 pm. 7/28/14I just witnessed an object in the sky in Mt.Shasta, CA. The location was at Lake Siskiyou camp resort. I witnessed the object from the beach looking out the window of my cooking truck. The object looked like a piece of mercury or metal drop in the sky. The object was reflective but it wasn't from lights coming from the object. It looked like it was reflecting the sun. The object looked out of place which caught my eye. I stared at the object for about 15 seconds. It didn't move like an aero plane or helicopter. It moved like a mouse on a computer screen but in a perfect straight line. I was losing sight of the object from the window, where I'm at the sky is wide open. At is a partly cloudy day, but there were no clouds in the path of the object. I ran outside to try and track the object. When I ran around the corner to look in the direction of Mt.Shasta where it looked like the path in the sky that the object was traveling it was gone. At the speed that the object was traveling I still should have been able to see it in the sky if it was a plane or helicopter. It was just gone. The object made no noise. It just looked out of place like it wasn't flying in the sky but almost like it was a fly on a TV screen, part of the view you're looking at but not in the screen? I looked around at all of the people on the beach, but it didn't look like anyone was looking up at the sky. This is my 4th object I've seen in this area that I would say is a UFO. First one I've seen in the day.
