Apparently ( keep in mind , I'm not good with the car talk ) , a rod blew , creating a spark in the engine which set the oil on fire . We grabbed all our stuff out of the car in case it blew up , and called the fire dept . We also called Aaron and Amy to turn around and come rescue us .
Why did they call the fire dept ?
