Use Nature To Fortify The Border WALL - Plants With THORNS
I had a visualization of planted BRAMBLE Bushes on either side of the Border WALL. Those suckers have really Sharp Thorns, it's Mother Nature's natural Razor Wire and it spreads. So I was curious as to which brambles have the most serious thorns….
Cactus have spines but Mexicans & Central Americans eat them for food and cactus provide water so it's not as good a deterrent as Thorns because big Thorns will really cause pain.
