From new FaceBook event page:

The City of Richmond was chartered on July 19, 1782. It’s
fitting that she shares a birthday with our dear colleague,
T. Tyler Potterfield, who was once heard to profess her “the greatest city in the world”.

This year we’d like to celebrate Tyler and his beloved City of Richmond by volunteering on their birthday, July 19. We’ll be working to help clean up and improve a section of the Riverfront, a place in the city Tyler treasured, at the Pipeline Walk and Overlook. We’ll also plan to have lunch together and a chance to celebrate Tyler’s legacy through conviviality, not just service. More details will be forthcoming as plans are finalized (and we’ll share them here).
