I have a large collection of books about the railroads that ran through the places where I've lived - Long Island, New York Central, Boston & Maine, Boston & Albany, New Haven. I find it interesting to read about and look at photographs showing the railroads and the USA in the years before I was born and when I was a youngster. It brings back memories of life in those days - the cities, the industries, the trains, the cars, the clothes, the jobs at which people worked - before computers, internet and cell phones. An excellent way to learn about the history of the United States and put one's own experiences in perspective.
