I'm a doctoral student at Yale, where I study environmental policy and economics. I've traveled extensively in the US, South America and Asia and a bit to other parts of the world. Before this, I worked in environmental consulting in Colorado and California, helped start a business in Ecuador, and traveled for a couple of years working on organic farms in the northeastern US, including one farm where I built an 8-foot-square "hobbit house" into the side of a hill. It is still standing, 16 years later.
I like airbnb (and vastly prefer it to hotels) because I like people. The best thing about traveling, for me, is getting to know people and communities. That said, I'm pretty self-sufficient in most of my travel, so I don't usually expect much interaction with hosts - but if we have a chance to talk and find we have something interesting to say or something in common, I'm always happy and grateful for that.
