Our parents called them "the Bible Club girls," even though Hazel Simonton and Jean Clark had strands of grey sprinkled through their dark hair by the late 1940s. That's how people referred to women, especially single women, back then.Every Wednesday after school, the Bible Club girls came to our church in the Bitterroot Valley of Montana. The pastor had built a fire in the cast-iron furnace in the back corner of the church, but the building was still bitter cold when we arrived at three-thirty.
