We spent two weeks in Argentina in October and are planning another trip next November. Needless to say we loved it. One comment on the counterfeit bills is this is not just a tourist scam. While shopping in San Telmo a clerk carefully examined our bills. We asked what she looked for and she showed us. She also showed us several counterfeit bills that had been passed at the store. It seems that the owner is elderly and has poor eye sight. This is apparently understood and makes him particularly susceptible to the scam. Although we did not experience the taxi scam described in this thread we did experience another one. One evening returning from dinner at La Estancia to the Hilton I noticed the meter seemed to be racing . When we arrived the bill seemed to be out of line with previous taxi fares. Well it was late, diner was good, the wine was better, life was good, and what is the big deal about a $9 cab fare? Next time the same ride was maybe $3. If this is as bad as it gets, no problem.
