Many organizations have iconic containers for monetary donations — the Salvation Army has its Red Kettle, Unicef its Trick-or-Treat for change boxes. But the Muscular Dystrophy Association takes a unique approach to fundraising, collecting dimes and dollars in sturdy rubber boots. On Thursday afternoon, 16 members of the La Crosse Area Professional Firefighters IAFF Local 127 took turns holding out their boots to passerby, collecting donations on behalf of the Muscular Dystrophy Association. The Fill the Boot campaign, established nationally 60 years ago, has raised more than $607 million for researching cures and developing treatments for the life-threatening muscle disease, which can cause difficulty breathing and swallowing, heart problems, scoliosis and limited mobility, including losing the ability to walk. There is currently no cure for the debilitating disease.
