I believe that the Tennessee Senate has passed a bill getting rid of gun free zones in parks

Handgun Permits - Allows any resident, who has a valid handgun carry permit, to possess his or her handgun while within the boundaries of any state park. - Amends TCA Title 39, Chapter 17, Part 13 and Title 70.

Passed SB2143 as am., Ayes 23, Nays 5 5/31/2007

Thanks very much to Jon Shell for sending me this information.
