Most counties are known for what they have. In Macon County's case, it is interesting to reflect on what the county has NEVER had.
Macon County is one of the few counties in Tennessee that has never had a railroad line.
Macon County also has no major river.
Therefore, Macon County has historically been a very isolated place.
One thing that Macon County DOES have, however, is clear water. There are, beneath the ground in Macon County, natural springs that produce water that is very clean and contains lots of minerals. In the old days (1920s, 1930s, for instance) people would come from all over to vacation near these springs.
Today, a big company called Nestle takes some of the water in Red Boiling Springs (a small town in Macon County), bottles it, and sells it at your grocery store.
Here is the Macon County Courthouse.
