We were driving over the Mid Bay Bridge in Okaloosa County, Florida going North. It was kind of round green. It was like someone just turned out the light when it ended. My son saw it first so I'm not sure how long it lasted but I saw it for maybe 3 seconds. We thought it was close whatever it was. That's why we didn't think it was a meteor at first sight. We live near Eglin AFB and knew it wasn't a plane light. As we were driving home we found out there was a meteor shower tonight.
