Sidewinder
Sidewinder is the closest town to the Overlook Hotel, located forty miles east over roads that close from late October or November until April. It is the last link to civilization before the mountain winter sets in, and its isolation becomes absolute once the snow arrives. The town contains a public library, a drugstore with a telephone booth, a Conoco station run by Larry Durkin, and a doctor's office where Dr. Bill Edmonds practices. The road from Sidewinder to the Overlook passes through Sidewinder Pass, beyond which snowplows do not go in winter, and the highway is closed from Sidewinder all the way to Buckland, Utah. The telephone lines between Sidewinder and the hotel are aboveground and go down almost every winter, often staying down for three weeks to a month and a half, leaving only a CB radio as communication—until Jack Torrance smashes that as well.
Role as Supply and Service Hub
Sidewinder is where the Torrances obtain essential supplies and services before and during their stay at the Overlook. Jack Torrance visits the Sidewinder hardware store for nails and a bug bomb to deal with the wasps' nest on the roof. Wendy Torrance drives the hotel truck to Sidewinder for milk and Christmas shopping in October, and later takes Danny to Dr. Edmonds's office for a medical examination after his trance and the wasp stings. The Sidewinder Public Library holds newspaper files that Jack uses to research the Overlook's scandalous history, including the gangland murder of Vito Gienelli in the Presidential Suite. The town's drugstore has a telephone booth where Jack makes his confrontational long-distance call to Stuart Ullman in Florida, and where he buys and chews Excedrin tablets, a habit from his drinking days.
Isolation and the Winter Barrier
Once the great snowstorm begins, Sidewinder becomes unreachable. The road between the Overlook and Sidewinder disappears under an even blanket of white, and the highway is closed. The Torrances are cut off for weeks, with no phone, no CB radio, and no way to drive out. When Dick Hallorann finally reaches Sidewinder by snowmobile after a harrowing journey from Denver, he rents an ArcticCat from Larry Durkin at the Conoco station, who warns him that the road is closed and that he will never make it to the Overlook. Hallorann's arrival in Sidewinder marks the beginning of the rescue attempt, but the town itself remains the last point of safety, the place where Dr. Edmonds and a rescue party with extra clothes, brandy, and a snowmobile eventually meet the fleeing Torrances and Hallorann after the Overlook's boiler explosion.
Narrative Significance
Sidewinder functions as the boundary between the ordinary world and the Overlook's supernatural domain. It is the place where normal life continues—where people shop, see doctors, and read newspapers—while the hotel becomes a prison of snow and malevolent forces. The town's proximity yet inaccessibility during winter underscores the Torrances' entrapment. Jack's research in the Sidewinder library reveals the hotel's dark past, but also triggers his obsessive need to write a book about it, which leads to his conflict with Al Shockley and his growing paranoia. Sidewinder is also where Danny and Wendy have their honest conversation in the truck, where Danny admits he is afraid and where Wendy decides to stay despite her fears. The town represents the last chance to escape before the snow closes in, and its doctor provides the only professional assessment of Danny's condition—an assessment that dismisses the supernatural but cannot explain the bruises on Danny's neck or his knowledge of his mother's dead sister.
