Stoning Satan

I was looking through the world in pictures on BBC's website and this image of the Muslim's casting stones at this pillar was pretty striking to me. Even more interesting was the further knowledge from the caption that: "Muslim pilgrims cast stones at a pillar, symbolizing the stoning of Satan, in a ritual called "Jamarat", the last rite of the annual Hajj in Saudi Arabia." Well, you learn new things every day; I'd throw a stone at Satan any day if I could even if it were symbolically.
