The Pennsylvania Conference for Woman is expecting 12,000 attendees in Philadelphia. The Southeastern Pennsylvania Transportation Authority (SEPTA) is warning of possible higher ridership on Tuesday for the morning and evening rush hours on the Regional Rail lines.

The sold-out October 3 event is at the Pennsylvania Convention Center with more than 100 guest speakers scheduled including Michelle Obama, former first lady, and Shonda Rhimes, creator of hit ABC series.
