August 11th – An afternoon recovery ride around Chasewater and Lichfield to keep my legs moving. At the canal by Catshill, there appears to be a film on the water. It always concerns me when I see this, as folk tend to think it’s pollution: it is, and it isn’t. It’s perfectly natural, and not man-made. The film is fibrous seed matter from thistles, willowherbs and other wind-seeding plants.
An odd phenomena that soon passes.
