Two years ago I had a utility trailer being towed through the neighborhood by an 4-wheeler ATV with just a ton of kids jumping on and off.
Aside from that, I've never seen anyone driven. They're all on foot. We're in a kinda pricey suburb of Chicago.
This year, we had 39. I know because we had 9 packs of M&Ms left from a 48-pack. (It was a bit nerve-racking around 7:30. We decided to hand out soda if we ran out.)
Semi-related, how many of people's trick or treaters needed a good kick in the butt?
Of my 39, I had one that was too young to talk much (but made up for it in cuteness) and three who were plenty old enough but couldn't manage a "trick or treat" or a "thank you."
One of those three (travelling together, so probably all a product of the same dubious parenting) managed a "thank you" after I called out "you're welcome" to her rapidly receding back.
Another of the three apparently didn't think I made it to the door quickly enough and decided to open it himself and come in, presumably in search of candy.
