Here's the story of Daniel Price, a man who lives in a hobbit hole (yes - it's from last year, but still very neat):
Here is a man who has the time and space in his life to watch and wait patiently to bring a new friend into his hobbit-like world. In third world countries where people value people slightly more than money, this is common. In a white western middle class America, to stumble across it is a delightful anomaly. [...]
Further along is a tiny arched door set into the side of a grassy embankment. The door is about two and a half foot square, and though it's just big enough to crawl through on one's stomach, it's solid and curiously inviting, He pushes back a flap of flywire and turns on a light, motioning for me to crawl in.
