Any advice on what I need to know about country living/owning property?

Can't say about California, but here in Missouri, I describe 5 acres as too much to take care of, but not really enough to do anything with. I do have 5 acres, but it's mostly woods. Still yet, I mow a little over an acre, which takes about a couple hours a week. One nice thing about having it though, houses are not stacked on top of each other.
