K: Curious to know what you thought of South America? I only know two people personally who have been down there and both were mugged, though not in Argentina.
My parents, who are in their mid 70s, have been on three round the world trips - they go for 6 to 9 months at a time - seasoned travelers and divers. They were on dive tour in Quito, Ecuador a couple of years ago on their way to the Galapagos - and my dad was mugged in broad daylight, with the guide and many other people only feet away from him. He was not hurt, only very startled and it happened so quick he barely realized it.
