I'd be curious to see an actually decent nationwide survey done to measure rates of trick or treating, especially breaking it down by age group and geography.
It's hard to tell how people in general feel about the holiday when you're limited by what's going on in your specific neighborhood.
Regardless, Halloween does feel kinda overlooked. Especially from an adult perspective, where it's mainly viewed as an excuse to throw candy at girls wearing skimpy costumes.
Which can be fun, but I'd love a more rounded Halloween experience for adults. Touring spook houses, diverse costume parties, movie marathons, or even just sharing stories of weird experiences on autumn nights over a few mugs of cider.
