I found this photo of the Brooklyn Bridge subway station on the internet a while back and didn't know what I was going to use if for. Then this challenge came along about lines. And as you can see, there are plenty of lines in the photo. Train tracks are leading lines, red posts are straight lines and even the tiles on the walls are lines.
