Wind actually stopped during our night tucked behind the dune. 
Drove nearly 200km’s south amongst filthy towns, plastic bags and smokey air.
John drove more in the smoky smelly towns. Amazing and frightening way that trucks overtake they just assume that bikes and cars will move over onto the verge.
The dessert turned to cultivated land and back to desert
Checked google for the bridge in 45k’s, it is there and there the google car crossed it but it does have gates with big yellow sign hmm?
I sat up and got my photos a bit more up to date. Just need to upload them.
