About 1,100 people participating in a nationwide march against nuclear arms were walking under gray skies in the desert near Victorville, 70 miles northeast of Los Angeles. The California Highway Patrol reported that the marchers were proceeding without difficulties. The 3,235-mile march started a week ago at Los Angeles Memorial Coliseum and is still plagued by a shortage of finances. Marchers are hoping to inspire and educate people to a plea for a safer world. The cross-country trip to Washington is expected to take about nine months.
