Celebrate Earth Day in Rodney Square on April 22, from 11 a.m. to 2 p.m. Visitors will enjoy giveaways, free raffle items, and free native plants, while supplies last. They can also look over hybrid, or fuel-efficient cars and they can speak with dozens of vendors offering green products, services and advice. Kids will enjoy story time inside the newly renovated library. They can also meet WILMAPCO’s new clean-air mascot. This rain-or-shine festival is sponsored by the City of Wilmington, DelDOT, and the Partnership for the Delaware Estuary. Discover more at DelawareEstuary.org, or call (800) 445-4935, extension 106.
