About 270 people protesting a nuclear test planned for February 5th at the main entrance to the Nevada Test Site on Jan. 27, 1987. The American Peace Test group sponsored the protest. In all, 72 people were arrested on charges of public nuisance and trespassing but most were arrested for public nuisance when they tried to block the test site entrance by standing or kneeling in the way of oncoming cars. The protestors carried an extra sense of urgency because the Soviet Union warned that it will lift its unilateral moratorium on nuclear testing after the first United States underground nuclear test of 1987. Location is the entrance to the Nevada Test Site in Mercury, Nevada. (Rene Germanier/Las Vegas Review-Journal)
