Grab your oldest gear and trainers (flip flops won't last two minutes), goggles and gloves and prepare for the frantic battle of your lives. This unbelievable food fight will mean you'll never look at a tomato the same way again and will have to resist the urge to raid the salad lob a quick one across the room at home. This puts bun fights in the shade as you join thousands of people in the Spanish street to throw a hundred metric tons of overripe tomatoes in the most unnatural fashion at anyone you can. Just don't lose your camera; you will definitely want these photos. Your transfer transport there and back is arranged but maybe a slosh off in the river before you return might be wise.
