He isn’t moving fast enough to be serious but still, this is farther than I thought Trump would go. Sourced from Associated Press release.
“CADELL CONSTRUCTION CO., Montgomery, Alabama. (Concrete wall & other wall)
Its tan concrete wall is thick at the bottom and narrows considerably toward the pointed top. The other, also tan, has metal poles on the bottom, a metal plate in the middle, and concrete block on top.
W.G. YATES & SONS CONSTRUCTION CO., Philadelphia, Mississippi. (Concrete wall & other wall)
Its models are a darker brown than other prototypes and topped by round beams. Its concrete panel has a plain face; its metal one has a corrugated surface.
FISHER SAND & GRAVEL CO., Tempe, Arizona.
It’s the only prototype to be built entirely on site — as opposed to being hauled in. Its tan surface gradually narrows toward the top, like a long triangle.
TEXAS STERLING CONSTRUCTION CO., Houston.
The gray surface of the U.S. side is stamped with patterns of different-sized bricks, like a driveway or sidewalk at an upscale home. There is a steel plate on top with prongs that feature at three metal spikes, resembling an agave plant.”
Given the choices, I like Yates’ idea for corrugated surface and tube crossbar on top. Corrugation allows good thermal expansion, a necessity in the Southwest desert, and the tube crossbar is harder to climb across than simple spikes or barbed wire. There’s nothing for a grapple to hook on. Metal would also probably be cheaper & easier to repair than concrete as well.
