As I wander through the streets with my camera in hand I often like to play a game. I tell myself to look for things hidden in the landscape; hearts, faces, secret messages. One particularly low day, I looked up to see this, and felt like it was a sign from the heavens. More recently, I was walking with a friend who was overwhelmed with work and being pregnant and trying to keep up with all of it. She was in tears by the end of the conversation, not knowing what she should do. At some point we looked down and noticed that we were standing on a bike path that said "Slow down."

This week's challenge is to find a hidden message. It might be just what you needed to hear.
