David, I hadn't spotted that, I tried to enlarge that photo but the computer said No, at least without joining something that I didn't want to. I see the bike has the "Works" AK 222 number, and I wonder if it is at Dob Park, the ford entrance looks to be paved, and I think that the large rock in the middle is still there, I propped my 500T Norton against it to take a photo last year!
