Oak Park’s celebration of green living is set for 10 a.m. to 2 p.m., Sat., April 18 as the 11th annual Earth Fest returns to the Public Works Center, 201 South Boulevard. The event focuses on green neighborhoods and sustainable lifestyles. Protecting the environment will be paramount this year as Earth Fest commemorates the 50th celebration of Earth Day. Highlights will include dozens of eco-friendly vendors, activities for children, items for sale and live entertainment. Earth Fest also serves as the Public Works Department’s annual open house, with tours of the green-built facility.
