10. Portland, Ore.
The near-ubiquity of buses everywhere but the fringe outer neighborhoods makes Portland a pretty easy place to move without a car, but the rail-laden neighborhoods in the city's center are the strongest argument for ditching the wheels. Neighborhoods such as the Pearl, Downtown and University Heights within the Free Rail Zone get free streetcar service throughout the city's core. That puts movies, restaurants, supermarkets and even
within striking distance without having to pay a dime. The Max light rail line isn't free, but it extends rail reach a bit farther into the Northwest, Goose Hollow, Buckman, the Lloyd District, Hollywood and much of the North along Interstate 5.
