ST, on my way home just before we were getting ready to pull into the driveway, a flash of what looked like a bluish color, started lighting up the sky for a little bit. i said to mom what is that, mom said something like Is that lightening. I'm like that can't be lightening cause its winter and its cold, it was snowing a little bit earlier. well it didnt make any noise that i was aware. Mom says well all things on earth have an explanation to them. So do you have any idea's on what this could have been? Thanks, Josh.
