Final answer:
In 'Into the Wild,' Chris McCandless sent letters to friends, family, and Wayne Westerberg among others, which contribute to the narrative of his search for a meaningful life.
Step-by-step explanation:
In Jon Krakauer's Into the Wild, Chris McCandless sent letters to numerous individuals including friends he made on his travels, family members, and Wayne Westerberg, a man McCandless worked for and became close friends with.
The narrative nonfiction story provides an intimate look into McCandless's life and his interactions with the people he reached out to via letters as he sought a life of simplicity and self-sufficiency, akin to the ideals reflected in Henry David Thoreau's Walden. Through McCandless's correspondences, Krakauer paints a detailed portrait of a young man in search of meaning outside the conventional bounds of society.
