Reported a dead pine marten to the society on the hard shoulder just before the Severn bridge, Welsh side 2 years ago. Of course I had many questions asked to try to ascertain if it was definitely a pine marten. It was 100%, had a good look at it along with my wife while we trundled along the inside lane at 60 mph. Would have gone back over the bridge to pick it up if I didn't have to pay the extortionate toll and had to be somewhere soon. Traveled the same route the next day and thought I'd pick it up if still there but no surprise, it was gone, think someone had the same idea. It was in good nick when I saw it and obviously a full grown animal, probably a dog. May have escaped from somewhere but when I reported it was told that there has been sightings in Mid Wales but never so far south.
