If you've ever driven through Tulsa, you've probably seen one of those signature Up With Trees signs and said to yourself, "If their trying to plant trees, why are the signs made of wood?" We were thinking the same thing! The good news, we found out why when we produced this piece for Up With Trees. The Retro team zipped around the city shooting interviews, local volunteers and the beautiful landscapes that have been impacted by this special organization. Tulsa is a prettier place because of Up With Trees and we jumped on the opportunity to bring awareness to their cause.
