Myself and my Mother *(Name deleted--CMS/sg) were taking a walk through a local Golfcourse when suddenly.a blinding white light, softball size at arms lenght just appeared.It was approximately 100 FT. directly over my head.There was no sound at all.My first impression (but doubt) was lightning.I watched as it zigzagged back and forth four times.A small blue light trail seemed to follow it.Brilliantly white lights also flashed directly on us 3 times.Similar to a camera's flash.My Mother was bent down fixing her shoe when this first happened,but she looked up and saw the object during the 3rd flash.We both just saw the entire sight vanish into thin air and back to the night sky,as though it never happened.This is something I know was very special for me to witness.But it was also a scary reality to us, that the unexplainable (as we know it) really does exist! I should of had a camera since weve seen 4 comets in the same area over the past several years.
