Here is a brief article with a photogallery, on the website of 90.5 WESA:
The world’s largest convention for furries, those fascinated with anthropomorphics, returned to Pittsburgh over the weekend with thousands of attendees converging on Downtown.
Anthrocon includes workshops, acting seminars, costume-building, animation, writing, art, design, lectures and more. It has also traditionally included an annual fursuit parade, but this year marked the first time furries marched outdoors.
The convention began in 1997 with about 300 attendees before deciding on Pittsburgh in 2006. Organizers have returned every year.
