Although this article just says Yuma, the wall segment is in the Yuma Sector of the Border (very rural), rather than the around the urban area of the city of Yuma.
well, it’ a start
The urban area of Yuma is almost completely finished, or already on contract (except for a small Indian Reservation, which will be monitored by new tech).
Basically, the entire Yuma Sector of the Border (one of ten) is already funded or contracted for continuous Trump-style super barrier system - and dozens of miles there will get the awesome double barrier system, like San Diego got.
Thirty footers are towering barriers. Half of the people who fall from thirty feet will die, and they are dis-proportionally fit young men. Most people will not even attempt climbing something that high (akin to a fourth floor window). Trying to navigate a few coils of concertina at that height is particularly unwise.
