The Night Lights
This is a night view from Conshohocken, facing west towards Upper Merion. There is some kind of plant nearby, and more factories beyond. The streak of light across the middle of the frame is a highway. And if you look carefully, you can see the Schuylkill River running diagonally through the middle.
Don't be fooled by all the bright lights -- this is a very long exposure (like 15 seconds).
