I love TN.
Here, a gun store that has a no loaded weapons policy is the exception. This holds true even in urban areas.
I know of only one store that has such a policy, and how they stay in business is beyond me. (Hardly ever see anyone in there.) Other gun shops I frequent (all owned by just some guy, no chain shops here, again even in a city) tend to have multiple customers in at any given time. They still give mostly good service. (One is run by a true good ole boy. Every sidearm I have came from him.)
