Catwoman? Jessica Denardo of Upper St. Clair — dressed up as Catwoman — is suspended above Mellon Square as she starts to rappel down the 26 stories of the Oliver Building. “Over the Edge” created the rappeling as a fundraiser to benefit "Our Clubhouse," an organization that provides free emotional and social support for people touched by cancer.
