Www.uscarry.com is an excellent source site and there are usually links to states laws.
Me, I now just avoid places that consider me a slave or subject.
I live in north western PA and no longer travel to NY and all of the New England area, even though I enjoyed my time living in CT in the 70's & 80's while in the US Navy. Since then CT has gone gun control crazy, MA always was. I have no need to ever go to MD or NJ. I have traveled over half the world and a lot of the USA. I've been to the whole left coast, lots of beautiful country that I will not see again ;). But there is so much to see and places to go camping in the relatively free parts of the USA that I will never be bored exploring that ;)
