On Tuesday, communities across the nation will get together to celebrate National Night Out.

National Night Out is an annual community-building campaign that promotes police-community partnerships and neighborhood camaraderie to make neighborhoods safer, better places to live.

National Night Out was first established in 1984 by Matt Peskin of the National Association of Town Watch.

The first National Night Outs were fairly simple. In most communities, they were mostly “lights on” vigils with some basic information given to the community. The event attracted more than 2 million participants in Canada and the United States.

Today, National Night Out draws in more than 37 million people from 10,000 communities across North America.

With the growth comes a shift in focus. Now, NNO brings communities together with festivals, block parties, cookouts, parades and various other events.

Here’s where to celebrate the event throughout Mercer County.
