At Manhattan Project National Historical Park in Oak Ridge, Tennessee, you can tour the world’s first nuclear reactor. I mean, that huge panel on the right is where two guys would actually push in each of the radioactive rods. Crazy!!! It all seems so…unsophisticated, like they were just throwing things together and figuring it out day by day. Oh wait, that’s kinda what they were doing… This was one of the most intriguing national park tours I’ve taken.
