I passed this stop sign almost every day for 4 years on my way to high school. I pass it every time I take Pepsi for a walk to the park. There's nothing to distinguish this stop sign from any other. And yet, on this day, while looking up at the sky I stopped and said, "Wow." And I just had to take a photo.
What colour is your sky today? Take a little walk outside (if you can) and keep your eyes to the skies. Keep going until you find a contrast, no matter how "common," that makes you stop and say, WOW!
