Kevin went to start the jeep to warm it up to go home and it was parked on a downhill slope. It cranked and cranked and cranked and it wouldn't start. He thought that was weird because it normally starts right up. So he tried again and it let out a HUGE backfire. Kevin even saw the flash and started the jeep right after. Meanwhile, Sara, kids and her parents were inside and heard a huge BOOM and came running wondering if it was his pistol. Fortunately the jeep started up before they reached the door relieving that panic. As Sara came to the door she saw Kevin and her Dad looking under the side of the jeep at the blown up muffler we had just purchased last month. Kevin had only heard of mufflers being blown out and never thought he would get to see one. Clearly, he was wrong.
