On Saturday 23 July 2016 I was walking in Forêt Barade, near Rouffignac in the South of France.
I published an invitation to call me on that day between 13:00 and 14:00 (CEST).
When the telephone rang I did not answer the call but instead I made a photo of what I was looking at on that moment.
I then sent the photo to the number that showed up on my phone.
