I was out hunting for something red in threes in a bricked city. Most were just red lights, red shops and cars but not in threes. At a traffic light, I turned my head to the left and there they were, lined up for me to take a photo of them just in time before the light turned green.

My personal keyword would be bricks.

Thank you for the contest and thank you @wakeupkitty and @gems.and.cookies for the introduction to this contest.
