Even with GPS in hand, I can rely on my poor sense of direction to send me the wrong way. I may be on the right street, but at any intersection, it's normal for me to take the wrong turn.
I've learned to just go with my directional instinct, no matter how misguided. So far, I haven't walked off a cliff. Instead, I've been rewarded with discoveries that sometimes lie just a few steps off my intended path, like this fanciful creation parked at the door of a cycle shop on the rue des Boulets in Paris.
