Worked around Madisonville in Vonore 2 weeks ago and OCed everywhere.
Even had my first Police officer encounter. SHE didn't even bat an eye.
For Knoxville, I've had no problems. Carried everywhere I can.
Don't know much about Maryville.
Malls are a no no
banks are touch and go. Watch for signs. Most are posted.
Shops, Walmart, Target, gas station, ect. good to go.
Carry confident, watch for gun buster signs and you will be ok.
