Driving i78 east, there was what appeared to be a very large survey drone flying. it was so large, i was trying to determine if it was a plane or a drone. then i noticed something moving in a straight path, far above and beyond the drone. both the drone and ufo were headed west. the other object didn’t appear to have wings. there seemed to be a slight haze around it, like you would see coming off a hot road. it gave the object an almost translucent look. it was traveling at a speed of only about 80mph, i would guess. i only got to watch it for about 30 seconds before it disappeared behind the clouds.
