For instance, I contribute to the local volunteer fire department. The annual festival. The fireworks on the 4th.
I pull my neighbors out of the ditch when their car slides on snow in the winter. Hell, I snowplow my stretch of gravel with my tractor if the county isn't going to get to it for a couple days and my neighbors need to get to work.
Interactions are generally more cooperative, maybe even healthier, without the always-being-in-one-another's-face.
