We went to the Andalusia equestrian training place in 2007 on a ship's tour. It was very interesting. They take you around the facility, take you to the barns to see the horses and through the tack room where they have all of the saddles, sturrips, … that they use. You then go into the indoor training stadium where practices are going on. There were about 4-5 different horses being trained doing different things. We also went to a place that makes sherry wine.
