Take a look at the video, "Forgetting the Wounds of War", that shows what this group of volunteers does.

Team River Runner (TRR), was established in August 2004 by kayakers in the Washington, DC, area, and is an all-volunteer organization run by a council of kayakers and overseen by a board of directors. Working in partnership with The Wounded Warrior Project and Disabled Sports USA, TRR helps veterans of the Iraq and Afghan wars recuperating at Walter Reed Army Medical Center (WRAMC) find health, healing, and new challenges through whitewater boating on the Potomac River. While the focus of TRR's work is on soldiers recuperating at WRAMC, TRR also provides whitewater boating opportunities for family members as well as for other wounded veterans.
