Bee, I hear you loud and clear. We used to have a great community, back in the granola years. Hubby and I were on the fringes of that crowd, but there was a lot of community back and forth, give and take. The property directly across the front end of our little dead end road was about a 100 acre parcel. 4 families joined to buy it communally. Each family had a few acres for their personal property, and shared ownership of the remaining acreage. I don't know if the community acreage has "been dissolved", but all initial owners have moved on. We had a little co-op store on that community parcel. DH and I raised layers and meat birds, splitting the labor and birds with one neighbor in that group, then doing the same thing with a neighbor up the street. One of the "up the street" neighbors does a great job looking after the needs of the folks around them. He has a tractor, and chain saw, but they do no farming. During the last major wind storm, he went and cleared a huge downed tree from a neighbor's yard.
For the most part, it's very difficult to develop those kinds of relationships. I do see it happening within my church community, and DH and I have been on the receiving and giving end of that a multitude of times. Groups of men/families will gather to cut and split wood, do yard work, put on new roofs, help someone move, winterize... One guy has a Kubota, and he does some volunteer work with that. We even have small groups that function on common interests. There is even an ice fishing group.
