Motocross is the second most physically demanding sport on the planet, yet it's not represented in the Olympics. Is it because the Olympics should only include human powered events? If that's the case, sailing should be out...Is it because it has a motor? I would think a sport that's so physically demanding would trump it's power source.
I'm not advocating Mx being in the Olympics, but I'm just wondering what makes an Olympic sport and where should the line be drawn?
