It is a big car junkyard in Wendell, Idaho, USA. There are over 8,000 classic cars from the 1920s to the 1980s.

That's my kind of collector .

The Great Stalacpipe Organ, found within Luray Caverns is the largest musical instrument in the world. Sound is evoked via stalactites being gently tapped across the three acres of the caverns.

We can thank Mr. LeIand W. Sprinkle of Springfield, Virginia, a mathematician and electronic scientist at the Pentagon, who in 1954, started a three-year project by scouring the cavern chambers and picking stalactites to precisely match a musical scale. Electronic mallets were wired throughout the caverns and connected to a colossal console.
When a key is hit, tone is produced via the rubber-tipped plunger striking the specific stalactite matching the note desired.

The Chicago River Reversal
Why it happened: In the late 19th century, Chicago's rapid growth led to severe pollution in the Chicago River, which flowed into Lake Michigan—the city's source of drinking water. This caused widespread illness and death.
How it was done: An ambitious engineering feat involved building a 28-mile canal that connected the Chicago River to the Des Plaines River, which is part of the Mississippi River system. By making the canal gradually deeper to the west, water was encouraged to flow from the river, away from the lake, and toward the Gulf of America.
The result: The reversal was a monumental success in terms of public health, transforming the Chicago River into one of the world's only man-made rivers that flows backward.

Fixed.

I’ve been there and listened to it. It was fabulous!
