A friend from KY  is headed to TN for the weekend.   He plans to be in Nashville some, but mostly in the Barlett area of Memphis.

What are the laws and practical restrictions of non-resident  concealed carry in TN?    

It is our understanding that TN has reciprocity with KY to some degree,   and TN has permitless concealed carry to   some degree.   But,  he mentioned TN has different levels of legal concealed carry, such as something like some sort of enhanced carry permit.   What are the different types of legal concealed carry and their implications?

Do signs carry the weight of law?

While my friend does not drink, he may want to go to a bar with friends.   What are the laws regarding carry in bars?

Is there any restriction on what one can carry, such as no NFA items, rifles, or whatever?

What about concealed carry while driving?

To help us  understand the situation in potential differences,   please detail some things a non-resident should not do.

Here is the situation in KY for comparison.

Federal laws apply:  no school carry; no federal building carry.

Vehicle carry is fine.

Signs do not carry the weight of law.

Some businesses by name can prohibit carry,  such as hospitals.   But all they can do is tell you leave if caught.  Any business can ask you to leave.   If asked to leave, do so.  Don't get a tressprass charge while carrying.

No carry in court houses.

No carry in bars.   Carry in restaurants that have  bars is OK, but do  not carry  at the  bar.

No concealed carry in sheriff offices or police stations.   Open carry is OK.

No carry in governmental meetings (generally).

Permittless carry is the same as KY Concealed Deadly Weapons License carry for the states purposes.   That allows swords, NFA items,  or whatever.

He is the type to have done whatever is legal in KY.   So, feel free to tell us what he as a non TN resident  "better not try in TN".
