Disneyland has been through many changes. Plus, its been open for 60 years, so Disneyland has a lot of history.
Opening Day
Disneyland opened on July 17, 1955. On this day, Disneyland was dedicated at an "International Press Preview", which was only open to invited guests and the media. The following day it was opened for the public, which featured 20 attractions. On the day of opening, it was not a day for Disney. Traffic was delayed on the two-lane Harbor Blvd. and the temperature, that day was 101 °F. During this time, there was a local plumbing strike which meant that Disney had two choices; have working water fountains or have working toilets. They obviously chose working toilets, which meant that there were no working water fountains. This led people to believe that this was a product placement for Pepsi.
Expansions
An expansion of the park was New Orleans Square, Critter Country, and Mickey's Toon Town
Added Attrations
A new ride that was added 16 years was the Haunted Mansion.
