We moved to a semi-rural area and set up a mini-farm about 12 years ago. We love it here...most of the time...but there have been many challenges, from arsenic in the well to a horse breaking a leg while running away from a falling tree that was hit by lightning. Most of the farmers we meet seem to have a permanently glum expression. Accidents and injuries on farms are very common; I've had many, but I've learned to be more careful, too. Lots of repairs and maintenance to do. I think most people would not blame you if you decide to give it a try and later change your mind.
The good parts can be wonderful: communing with nature and animals every day, escaping from traffic noise, growing food, getting fit from doing chores, hiking and birdwatching from your door anytime you want, watching people you love enjoy the beautiful countryside when they come to visit.
One more thought...there are ways to set things up that will make things a bit easier for you, so plan ahead. Some things that help us are good electricity, outlets, and hot and cold water in the barn, stalls that open directly to pens and grassy areas to help keep animals happy and healthy, good fencing, and strategically placed frost free hydrants. Best of luck to you!
