Things like White Sands Missile Range, NASA and the others need to go somewhere, it seems they picked some of the least hospitable lands that would have little impact on population, business and agriculture. It's not like they scooped.up.land like the Kaibab or Bob Marshal Wilderness. In fact the only articles I've read about hunting that area take place after it came under government control.
I can't see the border military zone expanding unless we actually have a war on the border and then we're going to be glad the military is occupying that strip. With established border crossing getting stricter and more and more old crossing routes getting closed the remote borders in NM and AZ are looking more appealing to the cartels to get their drugs into the country.
I'm not for closing off lands to recreation, I am for protecting our borders and keeping our citizens safe.
