While we, like every other green-blooded Philadelphian, love us some Instagram, we source a lot of our photography from our Curbed Philly Flickr pool because sometimes size and dimensions matter. In the last few weeks, you may have seen our Call for Photogs to submit to the Flickr pool. Well, we know at least one person did. Just like that one guy in high school who actually relied on physics and not Super Glue to reinforce his balsa wood bridge, Steve Perzan, whose photographs are featured here, really brought his A-game this week. Be like Steve. Submit to the photo pool. All the cool kids are doing it.
