I am writing this from my hotel room in Buenos Aires, full of thoughts about how this city has changed since we offered our first tour here nine years ago. 

It has certainly become more gay friendly and accepting, both in the mentality of the locals and as evidenced by anti-discrimination laws that have been enacted.  

The gay scene in Buenos Aires is better than ever, and you can go out every night of the week and find something happening.  

Also the exchange rate has become very favorable for foreigners.  Currently there is a double economy.  The official exchange rate of 6 Argentinian Pesos to the US Dollar that you get at banks and ATMs, and the unofficial exchange rate of 10 Argentinian Pesos to the US Dollar that you can get at unofficial exchange 
houses.   So, your spending money while in the country will go further if you pay with cash.
