If this discussion is still open, then may I recommend Leitchfield, Kentucky, in Grayson County. That is 1 hour from Louisville and 2 hours or so from Lexington. My family owns a decent sized house in the next town over (2100 sq. ft) that was about $175,000 when purchased in 1999. So basically, houses and land are extremely affordable. There are many acres to be had in Leitchfield...heck, nearly everyone owns at least 10 acres! There are no big shopping malls (only 2 strip malls), and only a few places to eat (fast food mainly.) No movie theaters, no nightlife whatsoever. It's a quiet, peaceful town that's very rural. It's got about 6500 people, and the majority are super friendly individuals.
