You've seen Apollo 13. Perhaps The Right Stuff. Perhaps some other documentaries. You will still not believe the size, scale and audacity of the Saturn V Rocket. And go visit now, because those [docents] who work there - they know all these amazing details and are so excited to tell you. They worked on those rockets! They invented all that stuff! They invented the machines to produce all that stuff! And they did it in about a decade. Simply amazing. Thanks, Lowell, for the fascinating details, and for encouraging my daughters to be scientists!
