Thanks Hugh, yes it is one I made. Zigzag is not really a common theme in my photos, so was scratching my head to find something. This sort of fitted, although I tend to thing that zigzag should be much more angular and sharp.
It fits the challenge perfectly. It took me ages to find anything and apart from the faint mountain path that had a slight zigzag to it, I could only find those boring road markings. Let’s hope the next challenge is a bit more easier 🙂
