Don't ever whine or complain about the smells. Whether it's pig crap, cow crap, smells of goats, sheep, chickens, etc. it's what you have to expect with farm life. Many people who move from the big city to a rural community think that it's gonna be nice and peaceful with the smells of clover and flowers in the air. Nah uh. There are pig farms, chicken farms, cattle farms, sheep, goats, etc that will stir up a bit of a stink; not to mention the stink that comes from spreading manure on the fields.
Oh and the noise too. Farm machinery make plenty of noise going around the fields, you will hear that every day, guaranteed. If you live by a cattle farm, expect to put up with a bit of bawling and bellering by the cows and calves when they are weaned, or are being herded and moved around every so often. At night it's usually quiet, though in the fall there will be harvest machines going through the night.
You might have a few unwelcome visitors turning up on your yard as well: deer, moose, rabbits, are some of the wildlife you have to expect will turn up to have a nibble at your garden plants and flowers. Don't be surprised neither if some stray farm animals show up on your property; just call your neighbor(s) and let them know their animals are out, and come and get them.
You might feel a bit lonely being out in the country, as you don't have close neighbors to visit with or a freind's house you can just walk over to. Driving to and from a place is a necessity; no trains nor buses exist in the country, nor will you likely be able to have a tow truck easily find you if your car gets stuck on a road somewhere. Walking to the nearest farm is your best bet for getting help if you get stuck.
Oh and lastly, don't buy an expensive BMW or even a little sports car to drive around and do your errands. You need a good pick-up truck to do the job, preferably a 4x4.
