This post prompted me to have another stab at this image's location so I spent today searching around CB's known locations on Google Earth/Maps, Youtube, Flickr ect.
The Hippy Market area in BSJ would be my best guess after what I've seen today. The area has all the elements as in the photos, reeds, same trees, earth colour, grassy verges. The only thing missing is the fencing. Also being one of CB's last known locations pre May 2007 gives the area a plus point. It could also be a million other places of course
Maybe too screen time for me today or I'm going mad(er), and not wanting to start another 'dog cushion' saga, but am I the only one that possibly sees a child wearing a light coloured shirt, head looking down, strapped into a child seat in this image? Look directly behind the driver seat.
