Of course I know tilt ups are poured in place -- LOL
So, we will have a tilt up spot every 1000 feet along a 2000 mile long border, and build cranes that can swing 500+ feet? LMAO.
So, now you need billions in site work and temporary roads made to move the erection (no pun intended) cranes for the wall.
Let's just invade Mexico and make a 20 mile DMZ and free fire border zone
This whole thing is fantasy land.
