Concrete, steel, or ?
Sorry if I strike a political cord without meaning to. I heard that the latest plan may be to build a steel wall,fence,barrier.... on the southern border. I would think that would be easy to deconstruct with a plasma cutter.. I'm guessing that many of you have thought along these same lines. I have estimated a large concrete wall to be about 10million/mile based on $250/yard for poured concrete. 40' x 4' with 10' underground. I am using New England numbers for the poured cement. I am not sure how much rebar would be needed. 5 billion would buy you 500 miles. Please help tweak the numbers - I could be way off. I would like to hear your thoughts on steel -vs- concrete -vs- ??? |

However..one of the additions to the "fence" is sysmic detection units. They are quite easy to place..its a well proven technology. Think of it as a form of "land sonar" The tunnels have been dug in the basements of houses in urban areas to other urban areas across the border.

I think a 20 ft chain link fence, lay Constantine wire for a width of 70ft then another 20ft chain link fence. Build a road designed to allow tunnel searching equipment to traverse. Boarder guards to keep watch for anyone trying to use equipment to breach. |

Here's a little more from that article: "People have such an instant thing about how North Dakota is cold and snowy and flat. ... In contrast, South Dakota is universally believed to be a tropical paradise with palm trees swaying on surf-kissed beaches. Millions of tourists, lured by the word 'South', flock to South Dakota every winter, often wearing nothing but skimpy bathing suits. Within hours, most of them die and become covered with snow, not to be found until spring, when they cause a major headache for South Dakota's farmers by clogging up the cultivating machines. South Dakota put a giant fence around the whole state to keep these tourists out, and STILL they keep coming. That's how powerful a name can be." Note, some of the facts in that article are a bit out of date -- what with climate change, the "covered with snow" part probably is no longer true. I think I got the central facts from the article (which was syndicated to lots of newspapers) as they apply to this ND/SD border fence topic, but for those interested the article also has numerous facts about North Dakota's image and attempts to improve it. https://www.miamiherald.com/living/l...gs/dave-barry/ article1934484.html -- jiw |
