This is awesome. When I am forced to travel stripped of my right to carry, I always remind my family to sue on my behalf should I be harmed. You know, like when I have to travel to California or Illinois. I don't patronize businesses that don't allow me to carry my firearm unless absolutely necessary (pharmacy, hospital, etc). I hope other states follow Tennessee's lead. Make owners take responsibility for "gun-free" zones.
Here is the Bill Summary from the TN General Assembly page:
