Where is Ronda's airstrip, or why does Ronda have an airport code (RRA) if it has none?
Apparently, there is an airstrip a roughly 4 km east of the town, as confirmed by an IGN map, IGN aerial photography, and Openstreetmap (Thanks Muzer).  It does not give the impression of active use; a Panoramio photo shows a field of sunflowers.  Its full name on the topographic may is Pista de aterrizaje de CMA, which means Runway of the CMA, where CMA may be Consejería de Medio Ambiente, ar the Andalucian government's Ministry of the Environment (thanks Henning Mankolm).
