It's amazing what you notice when you are on a mission, deliberately looking for something specific. All these curves were part of "Fort. Cougar" on the school playground. Being able to get pictures while the kids were using the equipment made for a much more interesting composition.
GREAT curves -- what great creative thinking to recognize curves when you see them ( these would have "gotten past" me). LOVE the one that the little boy is playing on that looks like a giant auger.
