Telling SEPTA why you “SEPTA Philly” is a snap – literally. Now through noon on Friday, December 21, customers can use Instagram to show the authority why they ride the system.

Using the Instagram photo application, riders can take photos of SEPTA during their daily use of the system and caption the photo with what riding SEPTA means to them, along with the hash tag #iseptaphilly. Photos will be aggregated into a photo stream, which will live on the I SEPTA Philly home page, http://www.iseptaphilly.com.

Weekly prizes, including tickets to concerts, 76ers games and Blue Mountain Ski Area and SEPTA passes and gear, will be awarded for the best pictures.

“Since the contest launched on November 1, we’ve received hundreds of great photos on the Instagram stream and picking our winners has been tough,” said Elizabeth Bradford, the authority’s Director of Marketing. “We are especially seeking shots of riders using SEPTA’s buses, trains and trolleys to get where they need to go and having fun doing while so.” To view photos already submitted for the contest, visit http://www.iseptaphilly.com.

The Authority launched its I SEPTA Philly campaign in spring 2012 to attract the next generation of public transit riders – people between the ages of 18-34. In unscripted commercials, riders talk about safety, cleanliness, ease of use and affordability – topics raised during focus groups held with individuals in the targeted age group.

The photo contest is open to all members of the public. Submitted photos will be reviewed by SEPTA staff for approval before being accepted for the contest and the website. For more information on how to SEPTA Philly and to enter the contest, visit http://www.iseptaphilly.com.
