I'm in Rio now... visiting a fellow FTer, ajnaro.
My first trip to South America, its all new to me. But am heeding what is said here .. and staying alert. No cash except cards.
But as I'm travelling alone, its pretty hard to go anywhere that one would go as a local.. Sugar Loaf mountain etc.
So will stay in most of the time and venture out with friends for meals.
But its still nice to see the beach at Copacabana from the apartment here.
