Yesterday Fernando took me to a Coffee Park near town called Montenegro. I wanted to visit it very much because I never saw a coffee plant before. A lot of it grows in the central part of the country, around Armenia, Pereira and Cartago (the area is called a "coffee triangle"). Colombia doesn't produce as much coffee as people think (Brazil produces much more). Colombian coffee is famous not for quantity but for the quality and variety. We had a cup of coffee in the Park, the taste was amazing. Then we took a cable car to another part of the Park. From the cable car you can see large areas of the coffee plantations. We also had a ride on a roller coaster, visited farmer's house and we saw equipment used for processing coffee beans: http://en.wikipedia.org/wiki/Coffee
There was an area where you could see coffee plants from other countries, for example Brazil or Costa Rica, all of them looking a little bit different. It was a great experience for me.

In the evening we went to a birthday party of Viviana's mother (she is 52 now). It was quite an experience too, a lot of conversations in Spanish for me, and the serenata!! :)) - three older men singing very old and well-known Colombian songs. It would be great to do something like this in London for somebody's birthday, just that in London it must be expensive.
Viviana's family grows a coke tree in the garden. Well, I had a lesson about it too. Coke leaves are chewed by some indigenous communities and used as medicine, and they were also an ingredient of coca cola. Cocaine however is not only the leaves as I thought but also some chemicals which together make the white powder.
