This year is the 36th anniversary for National Night Out and the 31st year the Redding Police Department has participated. The evening is designed to heighten crime and drug abuse awareness, highlight local anti-crime efforts, strengthen neighborhood spirit and police/community relations and send a message to criminals, letting them know neighborhoods are organized and fighting back.Starting at 6PM this Tuesday night, city council members, department heads, fire fighters, and police officers will be visiting block parties throughout the evening. There will be barbecues, ice cream socials, and potlucks planned by various block groups. Besides the organized block parties, people are advised to lock their doors, turn on outside lights and go outdoors. Some communities hold the event on the first Tuesday in August, but October can be an alternative, especially when weather is too hot in August.
