As I do every morning, I was driving on route 88 North in Westport, Massachusetts at 4:05 am - on my way to work, when a softball sized glowing orb which was orange/yellow in color flew out of the woods on the other side of the road. It flew in front of my car (less than 50 yards in front of me). It proceeded across the road into the woods on my side of the road. I had no idea what the object was, as I have never seen anything like it. It appeared to be solid, yet translucent. It was moving so quickly that I couldn't follow it's progress after it entered the woods.
