Nope not a typo, its how in my small town we do Trick or Treating as there is one main highway and no sidewalks. Here are the photos.
We all pull into the church parking lot. Decorate our trunks and the kids go from parked car to parked car without concern of getting hit by a moving vehicle. Good time for parents as we can chat between visitors and more importantly everyone stays safe.

This looks like fun. You need to have some fun. Good for you.
