People in the Vegas area really like fireworks! Wow! In addition to the general "safe and sane" variety that we lit off in the street with neighbors (my kid's first experience with fireworks you light at home) there were fireworks in the sky everywhere. Down in the valley we could see them exploding all over the place. In our neighborhood, they were in the sky on streets in front and behind ours.
