45 years ago today one of the darkest days in Disneyland's history began harmlessly as a bunch of free spirits had a little too much anti-establishment fun in the park. Supposedly, the spark for this came from the dress code and pro-Vietnam War Bank of America's sponsorship of Disneyland.

The 500 semi-tongue-in-cheek flyers distributed by David Sacks told of the day's agenda:
Black Panther Hot Breakfast: 9am—10am at Aunt Jemima’s Pancake House
Young Pirates League: 11am on Captain Hook’s boat
Women’s Liberation: 12 noon rally to liberate Minnie Mouse in front of Fantasyland
Self Defense Collective: 1pm—2pm at shooting gallery in Frontierland
Mid-Day Feast: 3pm barbecue of Porky Pig
Late in the afternoon Yippies plan to infiltrate and liberate Tom Sawyer’s Island. Declaring a free state, brothers and sisters will then have a smoke-in and festival. Get it on over to Disneyland, August 6. YIPPIE!

As you can see, things began harmlessly enough.

When people at Disneyland got baked, they weren't making bread.

Things took a wrong turn when the establishment got tired of the rebels.

A riot squad on Main Street? Definitely not thematic.

It was a lesson learned by Park management that would hopefully never occur again.
