Visitors were hustled out of Mickey's Toontown at Disneyland yesterday evening after a loud explosion that turned out to be a dry-ice blast in a trash can. An police spokesman says the device, made from a water bottle, resembles other that have gone off around Anaheim in the last few months. "Unfortunately, it's an all too common experience," he tells the Los Angeles Times. Nobody was injured and Toontown was reopened a couple of hours later after the bomb squad had investigated the scene. (More Disneyland stories.)
