Hi, Sounds like a fantastic trip, I'm very jealous. I agree with Horsebox's comments, don't let other people's negative stories put off your trip. If you take sensible precautions and listen to local advice, then you'll be fine. Six years ago, I spent seven months travelling around South America including Peru, Bolivia and Argentina and didn't encounter any problems and had a fantastic time. Bolivia is one of the favourite countires I've been to and Peru and Argentina aren't far behind. PM me if you would like any more advice/tips. Dave
