John A. Petty II and Dawn H. Petty host the yearly Philly Seersucker Vintage Bike Ride and Picnic Social -- a ride where everyone dresses up in unique, vintage clothing, and ends with a city picnic -- taking place this year on June 23. The Pettys joined the Bicycle Coalition of Greater Philadelphia podcast recently to talk about the ride -- and why they once renewed their vows after another city's Seersucker ride.
