  • Mgbeley
    "We love this town, it is safe and very Norman Rockwell-esque. People walk around, parents walk their kids to and from school. These are “trick-or-treat” neighborhoods. The in-town restaurants are good, and it’s still close to Morristown for nightlife and commuting. "
  • Britany H. G.
    "Not sure. Just moved to the area. We hear there are great Labor Day events, and also 4th of July. ..... "
