From Pasadena Now!:
EVENTS: Join Your Neighbors for National Night Out. On Tuesday, August 5 neighbors and neighborhoods all over America will be opening their doors and gathering together for National Night Out. There are things you can do too, plan a block party, take your family on a flashlight walk, barbecue in your driveway or simply step out on your porch.
The Pasadena Police Department urges residents to take part in this unique drug-and crime-prevention event sponsored annually by the National Association of Town Watch and local Target Stores. This fun event is meant to strengthen neighborhood spirit and police/community partnerships, raise awareness of local anti-crime and anti-drug programs and, most important, send a message to criminals that Pasadena's neighborhoods won't tolerate crime.
This event brings together residents, law enforcement agencies, community-based organizations, businesses, Neighborhood Watch groups and local leaders. Worldwide, more than 34 million people participated last year.
Participation is free and simple: Turn on your porch light and step outside that evening. You can also invite your neighbors to a community gathering, or schedule a neighborhood association or Neighborhood Watch meeting, and invite your police officers to stop by. Call the Community Service Section of the Police Department at (626) 744-7659 or e-mail aramos@cityofpasadena.net-they'd love to visit your neighborhood. The benefits will last long after you go back inside.
ART: Yoko Ono invites the public to make a wish. Internationally celebrated artist Yoko Ono will present a major installation of her participatory work Wish Trees, in the large central courtyard at One Colorado. The installation will consist of a number of living trees selected by the artist, and which are identified with the environment or history of Southern California. Visitors are invited to write their wishes on pieces of paper and hang them on the tree branches. Public access to Ono's installation is free. Presented by the Armory Center for the Arts and One Colorado. On view August 1 to November 9.
