There's nothing like partying with a purpose. This past Saturday, the Greater Delaware Valley Chapter of the National MS Society held their Fourth Annual Preakness at the Piazza event, which attracted record numbers of attendees despite the stormy weather. Hosted by Fox29's Alex Holley and CBS3's Pat Gallen, guests enjoyed a live stream of the 141st Preakness Stakes on a 400ft LED screen, live music from DJ Royale, open bar, buffet, dancing and more.
