The park got such bad press for the event day that Walt Disney invited members of the press back for a private "second day" to experience the true Disneyland, after which Walt held a party in the Disneyland Hotel for them. Walt and his 1955 executives forever referred to the first day as "Black Sunday," although July 17 is acknowledged by Disney as the official opening day. On July 17 every year, cast members wear pin badges stating how many years it has been since July 17, 1955.(了)
