The Powerhouse Visitors Center in Kingsman features amazing sites inside and out. First off, while outside take some time to observe the trains across the street that you can actually walk right up to and explore. Once inside, they have tons of classic cars to view, some of which were already electric cars. Not only will you learn all about Kingsman, but you will also get to hear a lot about the state of Arizona as well. On top of that, there is tons of Route 66 memorabilia to observe. Not only are there tons of vintage route 66 postcards inside, but there are plenty of historic signs on the outside of the building to observe as well.
