Report Buenos Aires 2018 in Bids for the Youth Olympic Games Posted June 16, 2012 I just got back from spending a week in Buenos Aires. I can't attest for the athletic infrastructure of the city, which looks very dated on pictures, but at least they are trying to improve their transportation issues by expanding the metro system. Although the metro system/commuter train infrastructure is still incredibly limited compared to Mexico City, it is somewhat equivalent to what I saw in Rio. Just like Rio, Buenos Aires' main international airport is quite far away from the city center. On the other hand, there was an obvious foreign exchange black market going on. The new restrictions on converting Pesos to Dollars certainly had effects. I could not shake the feeling that things could go really wrong, really soon.
