PHOTOS: The Foundation Mat Concrete Pour for the New Comcast Tower

The largest concrete pour in Philadelphia history thus far (although some would beg to differ, see comment in the linked post) took place Friday night and continued on until Saturday morning. It was riveting stuff and apparently people gathered for the momentous occasion to immortalize it in social media heaven.

Below, some photos from the event:
