Ah, so pedestrians were still allowed along that road?
For the D-Day show in May, the road was closed to all traffic, pedestrians included, for safety reasons, but at 'Legends' there were quite a number of pedestrians there.
I normally travel down on a Saturday, arriving at Fowlmere camp site by about 13.00, and only go in to DX on the Sunday. Next time, I might give the road a try on the Saturday, because, as you say, it allows for some shots at different angles. That is, of course, if access is allowed, as technically, it's within the 'prohibited area' for minimum safety distance from the display axis.
