Allow me to directly refute you assertion that there are no other buildings:
From the legal fillings: US, v. Clive Bundy, US DISTRICT COURT FOR THE DISTRICT OF NEVADA, dated 9 Jul 2013
....In its complaint, the United States alleges that, not only has Bundy failed to comply with the courts orders that he remove his cattle from the Bunkerville Allotment and pay the financial penalties, but that Bundys cattle have moved beyond the boundaries of the Bunkerville Allotment and are now trespassing on a broad swath of additional federal land (the New Trespass Lands), including public lands within the Gold Butte area that are administered by the BLM, and National Park System land within the Overton Arm and Gold Butte areas of the Lake Mead National Recreation Area. The United States seeks an order enjoining Bundys unauthorized grazing on the New Trespass Lands.......
The trespass area is now into the Lake Mead National Recreation Area. The Lake Meed National Recreation area includes the Lake Mohave’s campground (http://www.nps.gov/lake/planyourvisit/campinglakemohave.htm) which includes “dock-yards” and “other buildings”
Oh, and before you try and say that is not a dock-yard, lets review the definition of a dock-yard:
A dockyard is an area that is designated for building, repairing, outfitting, and maintaining boats, ships, and other vessels. One may be built on land as well as on any body of water, and can be used by the military, a private party, a corporation, or can be used by the public, often at a predetermined monetary rate.
So two of the five restrictive conditions (assuming your own logic) have been met and I have provided proof that they have been met. I didn’t even need to go into park entrance buildings or maintenance buildings, National Park Service buildings, etc.
So once again, you are demonstratively proven incorrect ...and this time, I even used your own logic to show that you are incorrect.
.
Oh bless your heart, you used the Federal lawyers own statements to try and bolster your own...
Not that they are all that factual, but I’ll give you a B+ for effort.
