An 89-year-old woman has a special reason for participating in the Relay For Life.Dotti Moser is celebrating her 15th anniversary participating in the event, which raises money for the American Cancer Society. In 2004, Moser signed up for the first time. That year, she raised $1,445 - and she’s been raising money for the organization ever since.The mother of seven says the cause is very close to her heart. Her first child was diagnosed with kidney cancer when he was 3. Doctors gave him three months to live. He made it to 15 months. “Ah, yeah. It’s been, it’s been hard," said Moser. Last year, Dotti hoped to raise $100,000 in his memory. She just reached the goal."I’ve had some people come up to me and thank me for what I do, and that makes you feel good," she said.
