We have a rather loose knit community here, one young couple is sort of the coordinator for disseminating information around here. They also have a list of everyone who has a video security system and if and when something bad goes down hey let the PD have the list so they can check the recordings. We talk to everyone we can, some of the hipsters don't open up as much as say the Xers or Boomers but they are getting the community spirit too.
Try walking around and talking to anyone you meet on the street and say hi. Makes for fun too.
