I think it is generally a good idea in any case to just give your LTC to an officer at the same time you give him/her your driver's license. It avoids any mistaken impressions that finding out about it later might give him.
The general restrictions can be found at packing.org, if the web site is up at the moment. It goes up and down a lot.
There are other sites but none organized in as useful a way.
I was at Dollywood a few months ago. great vacation spot. Has signs prohibiting the carry of firearms at the gate. Private property has the right to set their own rules.
No carry in National Parks in any case, so much of the scenery is off limits to CC.
