Will be there for 3 weeks, about half the time we will be staying in Buenos Aires. My wife is from there originally. I don't speak Spanish but I speak bad German, of which there is a large population. According to Google maps there is a BJJ gym a few blocks away. Hopefully I can get one or two sessions in. Anyone ever been? Cool things to see? My wife has only been home once since 2001, and that was when her dad died this past summer, so she will almost be a tourist too.
