Structure

“I was driving down the highway at 70 mph and it was windy at the same time. Out of no where my sunroof window exploded shattering the glass. Luckily I usually keep the cover close. It sounded a gun shot that went off. There was nothing around me that would come down and break the window of the sunroof. It just happened out of no where.”
