This 65-year-old grandmother of three proves that unusual eco-action isn’t just for the young or (bare-it-all) outrageous. Browne, a retired Unitarian minister, blogger and gypsy at heart from Bethlehem, Pa., recently trekked 1,150 miles on foot from New Orleans to Rouses Point, N.Y., to raise awareness about climate change. For Browne, it was more than just a walk -- it was “a prayer, a meditation and an action.”
