From the Bridges board/category. [Bridge in Parque Nacional Fragas del Eume, Galicia, Spain (by RTH FOTOS). [Bridges have lots of "lines." Also, this bridge reminds me of train tracks that have lots of lines.
Cuevas del Drach, Mallorca, Spain summer of spectacular island with so much to see. The caves were one of my favourites, the tour ends with a 10 minute Mozart concert where the musicians drift in on lighted boats and perform for the crowd - beautiful!
