Sioux Falls, SD
Thousands of people gathered for the 29th annual Relay for Life at O'Gorman High School in Sioux Falls.
Participants took turns in the overnight walk to raise funds for the American Cancer Society in an effort to find a cure. Walkers began at 6 p.m. and walked in shifts until 6 a.m.
Many of the people walked in honor of a loved one who lost their battle with cancer.
