I live in an old mill town which straddles a large river in New England. Cobblestones line my favorite streets and I can check the time on a century-old clock tower which once ruled the lives of mill girls and canal diggers. It's entertaining to look out my window onto the main street at the people walking by speaking many different languages and all engaged in their own daily dramas. Do they ever think of the people who walked on those same stones 150 years ago? I like to.
