Instead of following your trick-or-treaters down the block in the car, consider walking the neighborhood alongside them.

Even fuel-efficient vehicles tend to be gas guzzlers at very slow speeds. If you're creeping along at 5 miles per hour, and frequently stopping to watch your kids walk up and down driveways, you could easily use more than a gallon of gas per hour.

If one in every ten trick-or-treaters convinced their parent or guardian to save one gallon of gas this Halloween, the fuel savings would total more than 4 million gallons-equivalent to the amount of gas that could be saved if 200,000 kids walked to school, instead of being driven, for an entire school year.
