 So it's not books. It's minutes. And so I think it's like 30 minutes times 10. I think it's 900. 900 minutes. 900 minutes to get entered in. 900 minutes of reading or doing activities. So it's not just about reading anymore. It's about an activity, an educational activity. And I used to have a friend of mine that said the biggest thing that the library district can do is get books into the hands of kids. And that's what Summer Challenge is about.
