My parents where both farm kids that had moved to the city and soon after they married while living about fifteen blocks from a big ten university my father looked out the kitchen window and saw a rabbit eating his green beans in their small garden plot. He looked at my mother and simply told her if someone asked yes she did hear a car backfire and he grabbed his rifle and shot what became that day's lunch. can't do that today cars don't backfire like they used to in the 70's....
