I am intrigued by the small glimpse into the entrance of the Rocket to the Moon attraction in this 1964 photo. What are those large spheres? A blast of vapor is escaping from side of the rocket (with Douglas markings at this point), hinting at the power of its liquid-fueled engine. The Autopia seems to be down, no young commuters are visible...in fact things look suprisingly calm for a June day. Maybe it's still early! And unfortunately, you can't see the Flying Saucers in this shot (futuristic pine trees block our view).
