Book excerpt: The Albany Post Road was the vital artery between New York City and the state capital in Albany in the eighteenth and nineteenth centuries. It saw a host of interesting events and colorful characters, though these unusual and extraordinary stories, as well as their connection to the thoroughfare, are oft forgotten. Revolutionary War spies marched this path, and anti-rent wars rocked Columbia County. Underground Railroad safe houses in nearby towns like Rhinebeck and Fishkill sheltered slaves seeking freedom in Canada, and Frank Teal's Dutchess County murder remains unsolved. With illustrations by Tatiana Rhinevault, local historian Carney Rhinevault presents these and other hidden stories from the Albany Post Road in New York's mid-Hudson Valley.
