[This could include the Opryland Hotel if its restaurant serves alcohol]
On the grounds of any public park, playground, civic center or other building facility, area or property owned, used or operated by any municipal, county or state government, or instrumentality thereof, for recreational purposes.
[This could include a convention center if it is government owned and operated]
An individual, corporation, business entity or government entity or agent thereof is authorized to prohibit possession of weapons by any person otherwise authorized by this subsection, at meetings conducted by, or on premises owned, operated, managed or under control of such individual, corporation, business entity or government entity. Notice of such prohibition shall be posted in prominent locations, including all entrances primarily used by persons entering the building, portion of the building or buildings where weapon possession is prohibited.
[Does this mean even the civic centers mentioned above must have a public posting at all entrances to legally prohibit CWs?]
