Every year, U-M students stay on their feet for 30 hours straight through Dance Marathon to raise money for kids’ rehabilitation programs at C.S. Mott Children’s Hospital. As Dance Marathon celebrates its 15th year of helping kids and changing lives, we took our cameras inside for a close look at the kids, the mission, the fundraising—and, oh yeah, the dancing.
