South Park, Colorado. You went to sleep in a town made of Lego bricks — which has ALWAYS been the case and nobody questions it. This morning, all five golden bricks that "structurally and spiritually hold the town together" are gone. Houses are going limp. A monster is being assembled. It is a school day, and you are not in school.
