Warning: Recycled News Story
I think most cyclists have a healthy hatred of potholes and avoid them whenever possible. I myself have used the Fill That Hole website to report some bad ones with some success. The recent freezing weather has made things a lot worse. I have noticed many more around and according to the CTC many more are being reported at the moment.
One person has found a novel use for them though. Art student Pete Dungey is trying to fill as many as possible with Primroses as a way of raising awareness through art. Good luck to him I say but, please...be careful!
