Since the USPS is not a federal agency, and since lots of post offices are not located on federal owned land, it seems to me that parking lot carry is often a non-issue. FWIW, I carry in the parking lot, but disarm before leaving my car to go inside as a precaution — since I never bother to check if my local post office is on federal land or not. Usually, I am with my wife, and one or the other of us stays in the car and locks the doors while the other disarms and goes inside.

Frankly, I don't care about the risk of being asked for ID as a witness to something. For one thing, the odds are small that it would happen. For another, I can always say I saw nothing, thereby decreasing LEO interest in me. And lastly, my experience with Grapevine PD to date has been pretty positive. My gut says that, even if I were asked for ID, and even if the LEO had knowledge that the parking lot was federal property, and even if I showed both TDL and CHL, the most I would receive is a warning that this is federal property and I'm not supposed to have a firearm there... ...to which I would reply, "Gee officer, I didn't know that it was federal land. Thanks for the warning, and I won't park here anymore with a gun in the car;" and that would be the end of it. I have always found Grapevine PD officers to be polite and reasonable.
