Wondering around the outskirts or countryside without good solid known local assistance/guide is asking for trouble, it is not when it will happen but where it will happen. The trouble comes in many forms from simple robbery to kidnapping or worst. If you stay in the major business areas and avoid placing yourself in "alone" situations you will be fine. Having said be careful or you might bring back more than you want, and I don't mean someone wanting to go to the land of the "big PX".
