Saving Mother Nature is important. Following the National Earth Day, the third annual Green Street Fair in downtown Plymouth keeps things in high gear Friday, April 30 to Sunday, May 2. This is a free event. Families will learn how to achieve greater fuel economy, what to do with old cell phones and even how to get organic in the kitchen. The fair encourages people to take strides large or small towards living a healthier life. Find more details in the Metro Parent Calendar and visit the Green Street Fair website.
