All I am seeing are gun laws on the State Level. Is there a list or good website that has detailed info on CC on a federal level?

One major question I am trying to answer is regarding government property ownership. Should I assume that
any place owned or operated by the federal government is a "gun free" zone? i.e. USPS

The USPS issue is argued back-and-forth on virtually every CC forum I've visited. Some claim it is 100% legal, others insist it is 100% illegal, and some claim it's ambiguous and depends on the circumstances.

IANAL, but I do not carry in USPS buildings.

As for assuming national buildings are non-carry, I would indeed do so until I positively verified with the given national agency that it was otherwise. OMO, YMMV.

blue,

If that is the section I think it is, continue reading. It has a list of exemptions right after.
