Massive accident caused by fan at Tour de France

While having fans back at sporting events is great to see, that doesn't mean that some folks aren't ruining things for others. Over at the Tour de France, several riders were reminded of this.

During a race, a fan was spotted holding a sign for the event, but clearly in the way of everyone. This caused one rider to take a spill, and he was followed by others.

I mean, come on. How in the world is this allowed to happen? That fan should be ashamed of himself, as injuries were surely recorded. Let's be smarter out there, people. This stuff can't happen.
