Every trip I take seems to bring me another lesson or two about what to do and what not to do during foreign travel. Failure to pay attention to these lessons would result in negative experiences, which of course, we all try to avoid.
For example, I learned to pack an extra pair of shoes after being caught in a rain storm in Ho Chi Minh City in Vietnam. Actually, it was a couple of days after the rain storm… when my blisters developed blisters, that the lesson sunk in. My shoes were still wet and my skin raw.
