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

Water, sewage, natural gas, are the main things I'd look at. You can always leave most of the land natural and just clear what you want. Clearing keeps the varmints away. Snakes, scorpions, raccoons, deer, coyotes, and the such. Can you shoot them without anyone going nuts? Will you and your wife adjust to everything being a little farther away? Groceries, a good hardware store, bagels? How do the people seem to get along with you and others?
