The Atomic Test Site Museum has opened just off the Las Vegas Strip. “The 8,000-square-foot museum, which opened in March, is the fruit of a decade of work by the Nevada Test Site Historical Foundation. The ticket booth resembles the site’s guard station; the movie theater looks like a bunker. “Countdown to next show,” flashes an ominous red clock. A roar and a blast of air greet visitors in the concrete theater.”
