Youth volunteers are helping to clean up Annie Williams Memorial Park in Bracebridge. The Town’s mayor Graydon Smith will be there today from 4pm to 6pm to help. It’s all part of the Change the World Youth Volunteer Challenge campaign for teens aged 14-18. The event will happen rain or shine. Last year, 3,400 youth participated in 39 events across Muskoka, North Simcoe and Barrie. Change the World is funded by the government of Ontario and is in partnership with the Ontario Volunteer Centre Network.
