There is a time and a place for everything.
Would Broad street in Nashville be a place for open carry? Probably not IMO. Would trail number 54 in the Cherokee National Forest be a place for open carry? You betcha. Unfortunately, Tennessee law makers can't seem to see the need for carry in a WMA which the Cherokee is, from the Georgia state line to north of the Smokeys.
Tennesse issues a handgun carry permit. You can carry open, or concealed.
