This and the following photo deserve explaination. There is a gondola that runs across the canyon. For the fireworks celebrating New Year 2000, and again this year for the Independence Day fireworks, a six inch thick rope of sparkler producing material was suspended well below the steel cable on which the gondola runs. At the approprite moment it was fired, and within three minutes produced the effect seen in the next photo, a cascade of sparks flowing onto part of the city below.
