Had excavating type logging machinery, had excavating machinery which I dug footings here in AZ till the bust.
Ran them all. JD, Cat, Fiat Allis, you name it.
Gimme a 992 and stand clear. All the spoils can go to build a berm on the American side with a channel between the berm and wall. Level the top of the berm off for a road for patrols.
Lets go..git er done.
I’ve tied rod, set forms, poured and finished concrete for everything but a bridge from blazing hot to freezing cold.
You prep it we’ll form and pour it.
Let’s not forget the antipersonnel mines in the channel!
We’ll need a stockade every 10 or 15 miles. With plenty of jail cells for the unlucky few who make it across the fence and through the....umm...channel.
