I'm in a family neighborhood and all the homes have 2 and 3 bedrooms. Still, we only get a dozen or so.
My neighbor said the numbers have been low ever since the pandemic, and that a lot of the kids go "trick-or-trunking". That started in 2021, and it's where a bunch of people park in supermarket and school parking lots from about 4pm until 6 and hand out candy from the trunks of their cars. He said these are state-sponsored events and the treat-givers are mostly city and county employees, so he figures they use tax dollars to buy the candy, refreshments, decorations, and gasoline for all the cars.
I've never seen it, so maybe they just did trick-or-trunks for a couple years. I just think parents do Halloween differently these days because they're afraid. (thanks to media hype)
