"Denver is not unlike a prison. Its inhabitants, too, have been sent there “to do time.” That which makes the position of the prisoner preferable, is the consolation that the State will feed him and that some day his time will expire. The majority of Denverites have no such cheerful outlook, Although arriving there with hopes of a speedy return, it’s usually imprisonment for life."
