On Saturday night, Piestewa Peak was lit with the costumes of several hikers decked out in LED lights and glowsticks. At least 25 people (members of the Arizona Cacophony Society) made the hike to the summit of the mountain, where a sprawling view of the valley at night awaited them. Some hikers brought balloons with them in hopes of 'lightening the load' on the steep hike to the top, while others brought a shot of whiskey to share upon reaching the summit. Participants wore everything from hulu skirts lit with 99 cent flashlights to Tron-like outfits made of blue glowsticks to light the rocky path ahead of them.
