Join Third Act PA at the Rivers Pathways Outdoor Community Classroom at Buchanan Park. We'll have art projects for children, advocacy for community solar, solar-stove demos and more. Other tables at the event range from mushrooming and bugs to nature journaling and the benefits of our urban trees. You can also add your touch to a collective art project and meet artists, environmentalists, scientists, poets and your neighbors.

Sun Day is a global day of action on Sept. 20-21, 2025, celebrating the unstoppable rise of clean energy. We’ll come together to showcase the power of the sun and wind, the energy sources that can power our world without pollution.
