Normally, I don't waste the time dealing with people like you.
The map clearly lables Colon as in Panama and the area outside of Colon to the extent the zone is applicable; and identifes the base as clearly being outside Colon.
And, the essential legal point here is that Zone, Base, City, and Hospital are all in the country of Panama, not in the several states of the United States and thus someone born there can't be a "Natural Born Citizen"--in fact, there is some doubt as to John's citizenship status at all--the statute under which he claims citizenship was adopted several years after his birth and is specifically not retroactive.
OK you’re right. All that time I spent in the Canal Zone was wasted now that I know a real geographical expert like you is out there to keep me straight.
How’s the weather out there in Area 51?
