Going through the elements of the historical and imaginary Old West in real and fictional Las Vegas, the intention of the essay is to show that facts and underlying psychology of residents and visitors on the one hand, and fictional characters on the other, make Las Vegas a successor of the old frontier. After having traced the history of Las Vegas, the essay analyses the increase in casino construction and the growth of the population residents and visitors that doubled in the past 14 years.
