Exploring foreign territory is an extremely fulfilling and relaxing experience. But as much as we would like to drift into that easygoing mode and soak up our novel surroundings, we shouldn’t drop our guard.

Being unfamiliar with local people and their customs makes us liable to deception, and nothing ruins an adventure more than crooked opportunists robbing us of our money.
