This past Thursday marked some special birthdays at Walt Disney World. Both Space Mountain and Carousel of Progress turned 40, and The Seas at Epcot turned 29. I visited the Magic Kingdom that morning to visit the two Tomorrowland attractions on this special day. Although the Carousel of Progress opened in this park on January 15th, 1975, it officially debuted at the 1964 World's Fair. I took this panorama shortly after enjoying the classic show.
