Retrofest kicks off what is unofficially known as Classic Car season in Chatham-Kent. This premiere event attracts thousands of classic car enthusiasts annually to downtown Chatham. Friday and Saturday, visitors are encouraged to head to Tecumseh Park where vendors, rides, retro-fun filled activities and entertainment are located. The highlight of the weekend is Saturday morning, when the downtown is then filled with hundreds of cars on King Street West and surrounding side roads from 10am-4pm.
