We do this every year my my parents neighborhood where I grew up. There's a lot of houses, a lot of kids, and you won't do better (for candy) anywhere else. There's not quite as many houses giving out candy as there used to be, and some streets are more or less active than they used to be. Most kids are being walked around by parents or other family, and this is where it starts getting weird to me.
I was on my own from age 5 on. Me and my friends got together in a group and it got really competitive. We didn't walk from house to house, we ran. We had 2 hours and 1- to 1.5-square miles to cover, full of houses. We learned to go to the further side-street houses at the end of the night because they wanted to get rid of the candy. We knew which houses gave out the best or most candy and which ones you were better off skipping. There were a lot of other kids, too, and you often had to stand in line at the doors. Trick or treating was big business for us kids.
The kids don't really seem to care now. I question if the kids are dragging the parents out, or if the parents are dragging the kids--in the case of my daughter, it's the latter at least half the time. She just wanted to see the firemen and the firetrucks. She could have cared less about everything else--we said as much when we got to the fire truck and, probably because nobody else was around, the fireman was nice enough to lift her into the truck to sit in it. She was stoked.
I'm not sure if I'd consider it a positive that they don't care as much about candy--that certainly would be--or a negative because they're no competitive, game-like experience. I see a lot of value in that personally and it's sad for me when it's lost.
My oldest son and his friend figured out that if they put on their masks on for the walk back to the car, then they could revisit every house for another round of candy since they were unmasked for the first visits.
