Everyone outside for the Grand Opening of Disneyland. More details in the link of the day it opened. I'd love to go there and walk Walt's footsteps some day, such a shame he never got to see Disney World.
1955 (July) Disneyland open to general public. Parking 25 cents, admission 1.00 / Rides cost 10 cents to 35 cents to ride. 50,000 had visited Park by end of first day and by end of week # grew to 1 million.
