Main Street by Sinclair Lewis

Kennicott had five hobbies: medicine, land-investment, Carol, motoring, and hunting. It is not certain in what order he preferred them. Solid though his enthusiasms were in the matter of medicine -- his admiration of this city surgeon, his condemnation of that for tricky ways of persuading country practitioners to bring in surgical patients, his indignation about fee-splitting, his pride in a new X-ray apparatus -- none of these beatified him as did motoring.

He nursed his two-year-old Buick even in winter, when it was stored in the stable-garage behind the house. He filled the grease-cups, varnished a fender, removed from beneath the back seat the debris of gloves, copper washers, crumpled maps, dust, and greasy rags. Winter noons he wandered out and stared owlishly at the car. He became excited over a fabulous "trip we might take next summer. " He galloped to the station, brought home railway maps, and traced motor-routes from Gopher Prairie to Winnipeg or Des Moines or Grand Marais, thinking aloud and expecting her to be effusive about such academic questions as "Now I wonder if we could stop at Baraboo and break the jump from La Crosse to Chicago?"
