Oh man, around here I live in a neighbourhood filled with children and young people, and just in general here trick-or-treating is HUGE. Which is weird~ Adults have parties too, but a lot of them just hand out candy. The bar scene is crazy on Halloween though! It's always super fun.
I went as Katniss last year I think, or two years ago. Something like that, and it was a really good costume. So I got compliments. 8D
