I say go for it. Like Alan said, at the minimum you have an internship, an overseas one at that plus the chance to experience new things. I lived outside the U.S. for about 5 and a half years spread between the Far East and Europe where I learned a lot about myself and how the rest of the world is that no classroom could attempt to emulate. For the first month or so it'll take some getting used to in regards to the weather, but within a month or so you'll be used to it.
The possibilities are endless for what you could experience while in Columbia from learning a new language, a new set of customs, different foods, new friends, perhaps even learn to enjoy farming. Who knows? The experience will be what you make of it.
I'm sure if you stow away cash like a squirrel does nuts for the winter you can make some decent coin as well. Will food, room and board be taken care of by your relatives as well?
