That site is so weird. And whoever wrote that article is also mathematically illiterate. Not to mention they didn’t link to any sources. So here is one they claim to have used:

https://ec.europa.eu/eurostat/statistics-explained/index.php?title=Foreign_language_skills_statistics#Level_of_command_of_best_known_foreign_language

This source says that 65% of 25-64 year old spoke at least a second language in 2016. The much lower number of 24% is when asked about proficiency, which can’t be compared with the US given Americans’ notorious overestimation of their own qualifications.

Most of the 25% of Americans (I couldn’t find a source for this) claiming to speak a second language is immigrants. I guess it needs to be said, but when people comment on the monolongualism of Americans, it’s about those who are not immigrants or first generation born in the US.

In my experience, most non Hispanics claiming to speak Spanish in the US struggle to hold even a basic conversation. And I have been to 35+ states, including door to door canvassing, etc.

I opened this post looking for coelacanth facts.

People in Montana do. Well, in their trucks, I don’t remember any cars there. I usually take mine off, I’m too tall to wear it inside the car.

It’s more machine now than man. Twisted and evil.

This is not redneck engineering, it’s how evening is attached to walls in the US as far as I can see. An ugly hole in drywall, and cover the rough edges with trim. I’m not sure what else you are looking for.

Something outside the wall could use minimal wood working and nails or command strips.

You mention you like picture frame mounts, so why don’t you use picture frames? You can get some used stuff for very cheap at Goodwill. Or get wood trim at home depot and cut to size.

Anything that’s not visible gets the glue gun treatment.
