Where Does The South Begin In Kentucky?

Kentucky is historically a border state, neither wholly Northern/Midwestern nor Southern. Depending on where you are in the state there comes a point in which you cross the border from the North or Midwest to the South. To my mind it occurs traveling south on I-75 about 500 yds. north of mile marker 131. At that point, you descend a significant hill and see before you spread out the northernmost part of the Bluegrass. The view calls to my mind the painting of Daniel Boone viewing what we now know as the Bluegrass from Pilot Knob. At the bottom of the hill is the Louisville Forge factory on the left as you travel south. From this point you are out of the hills of the Ohio River valley countryside of my native northern Kentucky and into the gently rolling Bluegrass.
