We don't really celebrate Halloween here in Finland. There's All Saints' Day, but it's not a big thing either. And it's not even necessarily celebrated on the November 1. But the US Halloween traditions have been leaking in. Slowly, through all the movies and tv.
It would be interesting to go somewhere in US and witness that Halloween I know mainly from pop culture. Maybe some day.
