If you find yourself in the mountain village in the Andes, or at a caravansary on the Anatolian steppe, you're not going to convince anyone you're a local. But in general, you should strive to disguise your tourist status. A fanny pack, a map and a guidebook attract thieves like ants to honey. Here are some hints for blending in:

• Walk with a sense of purpose--even if you're totally lost.
• Read your map before you leave the hotel so you can consult it as little as possible when you're outside in the street.
• You don't have to buy a whole new wardrobe, but try your best to dress like the locals. No dress shoes at the beach, people!
• Don't lug around your luggage, or even a heavily laden purse or backpack, except when necessary.
