Lots of such machines have been sent to the crusher at Albert Looms.
But... the problem is back on R54/68 at Mackworth.
Two youths on unlicensed machines were seen today and fortunately I had a camera with me and managed to get shots of both riders. I have reported the matter to the police and hope that the pictures will identify the riders and result in the machines being confiscated.
Please let me know if you should see these riders on the path.
