We live on a lake. It is 30 miles east and west to the closest major towns, and about 5 miles from a smaller town, (think grocery store two or three gas stations, four or five eating places) We could make do with the small town, except for medical. No hospital. Both larger towns have hospitals, and there is ambulance service in our subdivision.
That being said, you have to enjoy the "hermit" lifestyle. Our area is like a small town without retail. You get to know most if not all your neighbors, and life resolves around activities in the sub-division.
Now for kids and grand kids. We see them if we make the effort to see them. They are about 100 miles away. Not that bad, as grand kids are 14 and 21. Once the kids were in school the visits to the lake dropped off. However, that is our family. A couple of other neighbors see their kids more. But, I think we would all agree we see kids less.
Bottom line, you have to decide. As you don't have to make the move right away, try before you buy.
