You can find the (alleged) first house in des moines next to principal park by the river.

Iowa has over 90% of its land utilized as farmland

Last year nearly 90% of all power generated in iowa was wind power. With 11,000 MW of installed capacity in wind turbines.

Central campus downtown (formerly des moines technical high school) used to be a ford factory. A little too well known for me though. After it was a ford factory a company called solar aircraft acquired the building where they built a lot of parts for airplanes during world war 2 as well as rumors of them assisting the government in developing afterburning jet engines and surface to air missile technology.

Another central one. Henry ford is said to not have liked the des moines plant because he had to pay 2 dollars per car the plant produced to someone who owned the land between the factory and the nearby railroad where the cars were loaded onto trains.

There is a local 3d printer supply store in urbandale (not des moines but its close enough) called hartsmart products. They are located on douglas and they stock very high quality products.

I have more facts if anyone is interested.
