"Night Out" , a national crime prevention awareness event is set for August 3. Promoted by the Seattle Police Department it is intended to increase neighborhood support in anti-crime efforts, and bring neighborhoods together.
You can register your Night Out block party at http://www.seattle.gov/police/Nightout/default.htm and visit the Seattle Night Out Facebook page for more information.
If you are planning to hold an event this year here's a link to some helpful materials, http://www.seattle.gov/police/Nightout/Materials.htm
According to the SPD they had 1,200 people sign up last year.
Registration is required because the street is closed for the event and barriers with signage are put in place (as long as you don't use an arterial or an intersection for your event).
Typically the events are potluck with everyone bringing food and beverages for a group. Live music (not loud) is sometimes featured and neighbors bring tables, chairs and blankets.
It's a great way to get to know your neighbors better, talk about neighborhood security, even discuss disaster planning and preparedness.
Times for the events vary but generally run between 6pm and 10pm.
