The road train was loaded with old growth logs and I had my camera up to the windscreen to take a photo as we travelled slowly down a very steep hill. (On a websearch I found that one sawmill in the Injune district is allowed to log cypress pines so maybe that's what these logs are.)
And then this happened!! Another B-double passing over double lines, on a curve, on a steep hill. And then the car following did the same thing!
