Last weekend, 125 of us made the annual pilgrimage of repentance up into the mountains of Los Alamos, N.M., birthplace of the bomb, to remember Hiroshima. For the third year in a row, we put on sackcloth and sat in ashes to repent of the sin of war and nuclear weapons in a spirit of prayer and creative nonviolence. A monsoon downpour soaked the mountaintop, but just as we began, the rain stopped and the sun came out. Afterwards, our featured speaker, Fr. Roy Bourgeois, founder of the campaign to close the "School of the Americas," urged us to carry on our witness for peace -- that one day Los Alamos will be disarmed.
