I was in Spain this spring and while walking across the Puerta del Sol in Madrid I passed a metro entrance covered by a glass dome. There were reflections of the surrounding buildings that I really liked. Although it looks stormy the clouds were actually thinning out and blue sky was visible.
Later I noticed that my red camera is in the bottom right hand corner of the picture. Although it was unexpected I think that it makes a nice souvenir showing I was really there!
