Well, Uruguay is a country where gay couples can protect their marihuana fields with guns. It's pretty much the most liberal country in the south and highly ranked in the world. Funny part is that a lot of stuff didn't even have to be decriminalized, as they never criminalized it in the 1st place.  That being said, price wise it is actually quite expensive place to live (with relatively shit services for that price), esp if you want to be in Montevideo, and there are some caveats to being resident - very high property tax being one of them.
