Strange Goings On

While wandering round the "Mata dos Medos" above Fonte de Telha beach, looking for photo opportunities, I found numerous locations where, seemingly, a group of people get together to drink whisky and smoke cigars, leaving carnations and a dish/ashtray at the scene. This was one of three, apparently recent locations about 10 metres apart beside a path.

I found many more, so it is not a one-off activity. Very strange, I thought.
