Saw a friend, he told me about a scrap yard that is filled with old cars. So I went.
I started with an Isuzu Impulse, this was a good sign,
Not one, but 4 Land Cruisers where here. The Silver & Brown ones where Diesel.
A Previa & lots of hub caps.
A Plymouth Laser too. A few AW11s, a 944, some FB RX7's, & goes on.
Then for the engineering nerds, get ready. A Lift Lock for boats that was started in 1886, opened in 1904. It works using no external power, just gravity & water displacement. 141ft long, 33ft wide, & a fall of 65ft. It was the 1st lock to be built with concrete, & the (then) largest non-reinforced concrete structure in the world.
I’ll let wiki explain it, I’m not an engineer.
