Happy 57th Birthday, Disneyland!

1. July 17, 1955 was supposed to be "International Press Preview" day, but thousands of extra guests showed up due to counterfeit sold tickets.

2. On opening day, Disneyland consisted of 5 lands and 18 attractions, including the still-loved Jungle Cruise, Autopia, King Arthur's Carrousel and Peter Pan's Flight. Today, there are 8 lands and a whopping 58 attractions at the park!

3. Fifty-seven years ago, the freshly poured asphalt combined with scalding So Cal temperatures made the ground so soft that high-heeled shoes would sink into the pavement. Talk about a soft-open.

4. ABC helped finance Disney’s project, with the agreement to feed a live coast-to-coast broadcast of the big first day, hosted by Ronald Reagan, Art Linkletter and Bob Cummings.

5. Disney delivered his famous dedication speech, beginning with "To all who come to this happy place, welcome!" --  words that currently tick on the telegraph at the Train Station in New Orleans Square!
