Our daughter has lived in rural York for 12 years. No problems at all. It is a safe area of the county and is our capital.
I am not familiar with the schools but I do follow football at York Comprehensive High School. We have friends that live in Sharon. You will be in the boonies but it's not far from grocery stores, medical care and shopping.
I don't know where you live in NC but if you are looking to live in the country you will find that in rural York. In addition you will find the property taxes cheaper in South Carolina.
You will be about 20 miles from Sadie Mae's Cafe great home cooked meals and delicious homemade desserts.
