A local organization is promoting an "Edmonton Urban Games", possibly for 2010, that will feature at-risk youth participating in hip-hop, beatboxing (what is beatboxing? Oh. It's music. I thought it involved beating on each other) graffiti, and skateboarding.
Here's another great group, working at breaking down the barriers, and re-integrating some of our disenfranchised back in to the community.
The organization is Youth Restorative Action Project (YRAP), and is peer-run. Think about it. Committess of teens telling teens how to straighten out.
