I'm not at Staff College (missed that boat long ago and subsequently PVR'd), but I work in the vicinity. I'm amazed at the number of nutters cycling about Watchfield and Shrivenham in the dawn and dusk with DPM on, presumably pedaling between college and home. Some are sensible and perch a reflective bib on top of a little bergan, but some are oblivious to their invisibility. Guess what, DPM works. Some think by having a tricksy tiddly little LED flashing it makes them visible - truth is, when traffic is coming the other way, it's not much use. To the blonde who nearly went under my nearside last week, I apologise but I really didn't see you. No lights at all, full combats, you must be mad. You probably thought I was. Please wear a reflective jacket.
