To increase my own challenge, I restricted myself to capturing photos from Cleveland.

Task: Capture an image containing five similar subject in the frame.  

The easy way out would be to find a digital clock and at 5:55 pm incorporate it into the picture. But the whole idea is to find something new. Take birds and try to line them up in a certain pattern. Capture five people in a picture with some similar pose, expression or action. Or simply look for a landmark with a distinctive design element which contains five. I spent more time walking around and just observing than taking the images. However I feel that this is how you train your eyes and brain, to be perceptive.
