Hi all, we are new to this so came to consult the experts. We are going to Charco del Palo in Lanzarote and fancy being a bit exhibitionist in the sand dunes. This will be day time, outdoor, no car. How do we signal to others if we want them to come closer/stay back? How do we know if people want us to come closer to them? All help/advice gratfully recieved.
