Ooo very cool about Colombia.
We got the idea awhile back after talking to a man at a hostel in Pisac. He was working at the hostel and told us about his family's coffee farm in the jungle. He said that people could come out and work on it and stay for free. He gave us all his contact info, but he's never gotten back to us! So our thought was that maybe we could find a work exchange type thing. We're both really interested in learning about coffee farming and roasting, so we'd love that.
On the other hand, I found a lovely family farm on Air B&B that seems like it would be a little bit fancier. I think it's too expensive for us to do right now, but maybe someone else would be interested in it. https://www.airbnb.com/rooms/233392
