Very few door to door trick or treaters in my area. The high school puts on a trunk or treat in the parking lot and in the gym they have games and contests. The kids (big and little) have fun and it is much safer.
I don't know if I'd say most. There were tons if kids in our area and I don't remember anyone going to malls when I was a kid, which wasn't all that long ago.
Huh, must be a regional thing here. It is a more rural area, so you'd get more candy per square meter at the mall/church and that's very important to kids nowadays
