There are few, if any, links between the different layers and few known places for civic conversation. Largely a group of older Americans and families with young children. Most public events are not well known throughout the neighborhood. We lack any form of advertising that encourage people to participate. My neighborhood is not commonly the center of attention.
Many members come from various backgrounds and are more concerned with grades, classes, parties.
Sometimes people say hi in incidental places but that's it. Most keep to themselves. All knowledge of the community is through friends, TV, radio. No place that I know of where civic conversation takes place. We'll wave at neighbors when driving by or checking the mail, but I've never actually met any of my neighbors.
