Minnesota has a large ethnically Scandinavian population, so whenever summer occurs you start seeing elf doors appear on a some of the trees.
The elf live behind a small elf door that you place in your home. They lose their magical powers when they are seen by humans. That's why they spend most of their time behind the elf door and only come out at night to carry out their pranks, help in the gnome workshop or get up to other mischief.
S’quite charming. Strangely enough or not, I’ve not seen one appear in a neighborhood where people aren’t happy with one another.
