Streaking down the center of Vegas' historic Glitter Gulch gambling district, this five-block pedestrian mall is topped by an arched steel canopy. Hourly from dusk until midnight, the 1400ft-long canopy turns on a six-minute light-and-sound show enhanced by 550,000 watts of wraparound sound and 12.5 million synchronized LEDs. The shows are ridiculously cheesy, but mesmerizing enough to stop passersby in their tracks, especially drunks.
