LA LÍNEA/GIBRALTAR (Agencies) Members of the photographers' society of La Línea, AFAL, were invited to visit their counterparts on the Rock, the result of a cooperation agreement between the two groups. The Spanish contingent got to see many of the caves, including those on the Upper Rock, which are rarely open to tourists. Other common activities are planned, including an outing to take photos of Gibraltar at night. Forty photos from each group of this visit will be projected on Monday, March 19th. For its part, AFAL wants to reciprocate the kindnesses by inviting the Gibraltar group to take pictures of Semana Santa (Holy Week) in La Línea, plus what it is calling 'gastronomic conviviality' - or a good meal.
