Whilst this picture was starting to come together (beginning with the curve), I could hear David Bowie singing; yes Dave, there IS life on Mars! The curve is Wave Rock in Western Australia, one of many photos I took (see Surreal category header). The tyre marks in the sand were at Lowestoft, where the council smoothed the beach by redistributing the sand. I was out walking one day and noticed a big pile of tree trunks that were stacked ready to be taken away. Draped on top of the logs were some large, linked, articulated metal ribs. I didn’t know what they were but looked quite surreal. After some research I discovered they are Caterpillar Tracks that are wrapped around and fastened to the big pneumatic tyres found on Heavy Plant, e.g. cranes and JCBs. This gives the vehicle better grip and was obviously used during the forestry work that was done. I turned the landscape red, with the pink sky, in keeping with planets obvious attribute.
