Basketball and skateboarding are powerful tools for building community across cultures.

For tribal communities, these sports provide a unique avenue for cultural expression and mentorship.

Tuesday on Midday Edition, we hear from the author of the new book "Rezballers and Skate Elders: Joyful Futures in Indian Country" about his research into sports culture among tribal communities. We also discuss his work with San Diego State University's Center for Skateboarding, Action Sports, and Social Change.

Guest:

• David Kamper, professor of American Indian Studies at SDSU, associate director of the Center for Skateboarding, Action Sports, and Social Change
