If they can afford it they have a bullfight because it is still in their blood to make a sacrifice to God. This sacrifice represents the saving of Christianity from the armies of Mohammed, and the triumph of good over evil. All shops close for the feria and everyone ensures they have a good time. Each feria has processions, a pilgrimage to their Saint's altar, funfairs, music and dancing. In Spain you never see a drunken Spaniard, except at the feria.

I had travelled to Castell n de la Plana on the train from Barcelona in early spring. The views were magnificent. Rocky shores and sea on one side, plains and mountains on the other. As the train travelled through Tarragona the fields were pink from the fallen petals of almond blossom. You could tell the province of Castellon as the fields were brightly coloured from the fallen ripe oranges.
