My idea for starting a smile challenge is to paint rocks with people I know on them. I would then put it on my path up to my house and email them a picture and tell them where to find it. I would keep painting rocks and emailing them until the whole walkway is filled. Each with a person on one. So people would be able to see themselves and all of the other people in the neighborhood, that would make people smile.
