In 2017, this town of 13,000 ranked as the number one Safest City in America for the second year in a row! Located in Westchester County (a quick commute to New York City), Lewisboro boasts a crime rate of practically zero, with no violent assaults or burglaries. A plus for seniors? A public safety campaign that calls to check in on older folks who live alone.
