    "We have lived in the Danielson area for the past 25 years. This is a nice quiet area great for raising children! More of a suburb than a city. There are many local shops & restaurants available here as well as in the surrounding towns which are close and easy to reach. Dayville & Plainfield both nearby have great parks for children. Nature walks and parks can be found here in Danielson as well as most of the surrounding towns."
