There's an article in today's Philadelphia Inquirer about the writer's surprising and intense interest in Barbaro the racehorse.
As I read how this woman's interest in a horse propelled her to follow all sorts of paths the'd never have taken otherwise, I was reminded of unschooling.
Imagine if your whole life could be like this--pursuing whatever you're interested in. I think this article might explain unschooling better than all those others that have been in the news lately.
