This Halloween, children, tweens and teens will dress up in costumes and go door-to-door.

But their mission won’t be to collect candy – they’ll be trick-or-treating for good.

Check out these great initiatives:

Reverse-trick-or-treating

Trick-or-treating for cell phones

Trick-or-treat for Unicef (the tradition that began long before kids received piles of candy at each door)

Do you know of other trick-or-treat for good initiatives that we should know about? Did your family take part in something like this this year? Let us know. We’d love to hear your stories.
