It was reported that thousands of mules were used. Those pictures are photoshopped. Do a fact check!!!!
Ah, it got your attention.

You agree with they did use slide rules?

Happy New Year

I have it on good authority that the Hoover Dam had a safety factor of 10!

They wanted to build more dams and didn't want the first one to get in the way of more due to malfunction.

I still have a slide rule, somewhere, probably...
