John Muir of course is a hero and inspiring to most who travel the mountains but i'd say the person I admire and inspires me the most is Christopher McCandless, a man that could have been almost anything he wanted inside society yet choose to cast it all away, burned his money (literally) and took to the tramp life to seek the deeper meanings in life that society tends to shield from our hearts, though his death may be considered by many stupid or wasteful I see no failure in it and find he lived more in those 2 years of adventure then most do their whole lives.
