Metal wheelchairs colliding, balls gliding, and players falling -- sounds like some hybrid between bumper cars and football. It’s wheelchair rugby.

The head of the Olympic Public Authority (APO), Marcio Fortes, delivered his letter of resignation, raising concerns about Brazil’s handling of the preparations for the upcoming Games.

While in Washington D.C., the Turkish athletes played wheelchair basketball with American student athletes at local schools and organizations, including George Mason University and MedStar National Rehabilitation Network (MedStar NRH). The athletes traveled to the University of Illinois-Urbana for intensive wheelchair basketball clinics, and team building and conflict resolution activities. Throughout the program, they learned about disability sports culture in the United States.

Like listening to rock music in the 1960s, interest in such a uniquely American import marked the young skaters as socially suspicious, and sometimes for rough treatment by police and arrest, though their experiences were perhaps not all that different from confrontations between U.S. skaters and civic authorities concerned about the destruction of public property.
