Kennedy Space Center, Titusville, Florida (2015).
I do not use the word "awesome" much at all, reserving it for sights such as this: it's indeed awesome to stand in the presence of such an accomplishment as the space shuttle program. Here, two visitors to the Kennedy Space Center's new Atlantis exhibit provide valuable scale to this space craft that - existing in the real world - actually traveled to and returned from space. Simply amazing.
