Is there a list of “thru travel” rules by state?

[Daffypuck]

I’m not looking to carry any where on my travels, but want to know the rules for each state, where it pertains, when simply having a firearm in the vehicle (with a CCP of course). I’m traveling through all of NE as far south as PA and MD. I know the rules for NY, but what about the other states. I know their rules concerning reciprocity of actually carrying, but i can’t seem to find a list that tells of simple transportation through the state.
