Glasgow is a small-medium town, off of the 'Louie B Nunn' Cumberland Parkway (Future I 66 corridor!) with the typical fast food places, Walmart, Rural King, Lowes.
Bowling Green is about 30-40 minutes, Nashville 1.5 hours, Louisville about the same maybe a little more.
I'm 40 miles from Glasgow, but go there on occasion. I like the whole SC KY area, people for the most part a pretty friendly, it is not expensive to live here, still a lot of open land with cows and crops, but the wages in the area are usually not real high. You pay: state income tax, 6% sales tax, Real estate/land tax, personal property tax/vehicle registration. Sounds like a lot of taxes, but Real estate taxes are a whole bunch cheaper than I paid in FL or VA, I guess it is all what you are used to.
Land is available and fairly inexpensive for now, but the prices seem to be climbing.
PM me if you have specific questions.
