Do you visit POD (picture/photo of the day) sites?
National Geographic has a great photos on their POD. The above picture of Chicago was today's POD.

One reason I enjoy this photo is because I've been to that very spot. It's a recent addition to Chicago's Millennium Park.
Here's another photo from one end of this artistic bridge that I took:
