I first learned about him in an article in the Washington Post back in the mid 1980s. I enjoyed his sense of humor and everything, but what really got me hooked on helping him was the idea of providing free medical care for anyone who needed it. I was raising a kid by myself at the time and I couldn't get anywhere near as involved in what he was doing as I wanted to.
A couple of years later my life got really crazy and I lost track of him and his organization. I didn't think about it too much after that until I heard they were making a movie about him.
