After ten years at Troy, Odysseus sets sail for his island home of Ithaca and takes another ten to get there: blown off course, he meets a man-eating Cyclops, a witch who turns his crew into pigs, the Sirens, Scylla and Charybdis and a nymph who will not let him go, losing every ship and every companion on the way. Homer's Odyssey, composed around the late 8th century BC, has been read as a map for as long as it has been read.
Already in antiquity the poem's places were linked to real coasts, mostly around Sicily and southern Italy. Those identifications are traditions, not facts, and the ancient geographer Eratosthenes doubted them all — so most pins here are marked speculative.
In 1990 Christopher McCandless graduated from Emory University, gave his savings to charity and vanished from his family's life. For two years he drifted across America under the name "Alexander Supertramp" — working odd jobs, living in camps, paddling a canoe down the Colorado River into Mexico. In April 1992 he hitchhiked to Alaska and walked into the bush with very little food. He died there that summer, aged 24. Jon Krakauer told his story in the book Into the Wild (1996), filmed by Sean Penn in 2007.
The route follows his documented trail. The Stampede Trail is dangerous, and this route is not an invitation to retrace the last part of it.
Between 1947 and 1950 Sal Paradise, a young writer from New Jersey, crosses America again and again — hitchhiking, by bus and in borrowed cars — usually in pursuit of his wild, magnetic friend Dean Moriarty. Jack Kerouac typed the story on a continuous scroll of paper in three weeks in April 1951, and it was published in 1957. Sal is Kerouac, Dean is Neal Cassady, and most of the trips really happened.
The route picks out the places the novel names, from a rainy false start on the Hudson to Mexico City and back to a New York street corner. The novel gives towns and streets rather than addresses, so most pins mark areas, not doors.
