The places you can carry a weapon, concealed or not, is often confusing. Stores have to have posted signs, no carrying in Federal buildings, no guns in bars, school zones, etc etc etc. It's even more confusing on where you can carry while camping. One place for sure not to carry a gun, without a special permit is Indian Land. They will confiscate your guns. Bureau of Land Management, State Parks, National Parks, City Parks, military land, etc etc have their own rules. Often you cannot tell whose land you are in the middle of, unless you do research before you go.
You should do research. Do it... learn it and stay out of trouble in nature with park rangers..
It's not the wild animals a person should be afraid of in "the woods;" it the two legged assholes.
