We had a great evening last night with Freya of Wight and on their advice we took to Cadiz on foot - well, after we had taken the ferry ride across!!  Even we can't walk on water yet!    What a wonderful city and what a lovely day.  We walked miles and think we saw all the major attractions.    Unlike the Wizard of Oz, we didn't follow the yellow brick road but the purple one - marked along the streets of Cadiz for the benefit of tourists like us!
