Nearly 4,000 people braved the early morning wind and cold with the motivation of fighting lung cancer.
Our own Nydia Han again emceed the "Free to Breathe" Walk through Fairmount Park.
Lung cancer remains the leading cancer killer and the number of non-smokers diagnosed continues to increase.
Proceeds from the event go to research and education programs.
