Nine people were injured early Saturday when a garage roof on which they had been participating in a large party near California Polytechnic State University at San Luis Obispo collapsed, The Los Angeles Times reported. The injuries were not life threatening. Hundreds of students and others were at the block party, scheduled to avoid the double fines that San Luis Obispo issues within a week of St. Patrick's Day. The following video shows some of the party and -- at the very end -- the roof collapse.
