Bagpipes beats the boy racers

My son moved at the weekend. He and his mates were vacating a house in Fitzgerald Ave, which is one of the seats of boy racer territory in Christchurch. While I was helping, he told me of an incident some time ago, when a group boy racers pulled up about 2.30 in the morning, with car stereos blasting. So house occupants dragged their reasonably formidable stereo system to a front room window, and responded with a rousing rendition of bagpipe music. The boy racers ratcheted the level up a notch. So did the house. The boy racers revved it up another notch. So did the house. At which point the boy racers had to concede defeat (the house had a few more decibels in reserve). The cars moved on, and have never stopped there again.
