Cal wrote and asked about land bonds bought by the Mexicans, or land grants.
That is beyond my experience in real estate, we have none in this area.
I suspect that the thought is to the old land grants, made to the spaniards, before American took control.
This covers what I am thinking of:

My next thought goes to the giving away of our most valuable lands and water ways, to the UN, by clinton.
I do not know all the land, parks and waterways that he gave away and it upsets me to research it.

This should lead to a list of the UN owned property in the U.S., I know Death Valley has signs that say it is a UN property:

There are parks along the border in Arizona, that could well be controlled by the uN and if so, it is possible that an illegal crossing there would come under a different law.
Cal, you could always take my searches to a higher level.
I really do not have the right answers for this problem, except to say it is in the Communist Manifesto 1963.
Well, there's something I've never heard before.
