Went deep into the desert today. Drove about 80km from Riyadh, then 5km down some 'dirt' roads more like a dry river bed. This was the furthest that I could get.
I was supposed to be meeting a walking group, so felt quite save. It wasn't until I realised that it was the wrong day, and I was in the middle of no-one where with no phone signal.
The extra is some of the hills on the way
