German village dwarfed by heavy metal festival

Wacken Open Air is the biggest heavy metal festival in the world. It attracts more than 80,000 attendees each year - that's 40 times the population of the village of Wacken in Germany, where the festival takes place. Metalheads of all stripes descend upon the village every year for a long weekend of headbanging and debauchery. Host Carolyn Beeler tells us all about it.
