"But we were met with a new mishap; I twisted my knee. ... 30 miles still lay ahead of us; 30 miles of icy road between impenetrable forests, 30 miles of path through the wilderness without any human settlement, without any possibility of help if we couldn't go any farther, 30 miles of nothing but woods, snow and ice." (pages 60-61)
