Since the '60s, Ford has stored cars underground in a Kansas City cave

(Even random mentally ill people are likely to have access to firearms, and maybe heavy vehicles.)

Before cloud got big, I used to have a personal physical server colocated at a network facility, in a nondescript commercial building that you had to know was there, and turn off the main street to get to, with no signage I could see. (Also, biometrics scanners, when those weren't consumer things, and a waiting room that seemed to securely lock in visitors, in view of guards.)

I'd previously heard of non-government buildings without signage, for security reasons, so I figured that was it. Rather than not wanting to spend the money on a sign that would make it easier for customers to physically find, increase brand awareness, or raise their prominence in the minds of local officials before whom they might occasionally have business.

And, over time, you hear of other non-government unmarked buildings that are arguably "sensitive", for one reason or another. The ones that personally come to mind, historically that type has been threatened before (by, e.g., people angry at a company that they blame for automating away jobs, people who saw a movie involving blowing up records of bank loans and think that will work in real life, animal rights activists who want to free lab animals (and didn't see that other movie), eco-terrorists, people who are are mentally ill and found something conveniently located to fixate on). Maybe also no need to invite protestors?

There was a time when I believed this. But over the years, I've concluded that in many cases, that which is considered legitimate security is in fact rooted simply in ensuring that the attacker is lacking information, which is fairly synonymous with obscurity.

You think global trade amounts to 44 billion dollars per year?

The United States alone has a GDP of 29,000 billion dollars. World GDP for 2023 seems to be estimated at 105,000 billion dollars.

By that estimate, $2.2B / year is 0.000021% of global trade.

Not too far away (3-4 hours), the salt mines in Hutchinson, KS store a lot of Hollywood memorabilia.

One big plot point of "The Day After" back in the 1980s was that people sought shelter in the underground caves around Kansas City.

The Kansas City Ford plant manufactures more trucks/vans in a day than it can ship to their destinations, and Ford uses almost any surface lot it can rent (including a nearby amusement park's lot in the offseason) to hold cars until they can be transferred by rail or truck--it's very demand-driven. It's completely natural they'd use these caves as well based on their proximity to the rail and interstate transport near the river.

I don't see in the article anything that implies there's a cache of 1960s cars down there gathering limestone dust. That space would quickly be reclaimed for temporary storage of Transit vans awaiting their buyers.
