"That galvanized the Free Speech Movement. That was the start of the hippies, but it was also where more radical student movements came from. Black power groups like the Black Panthers -- and later gay rights groups like the Pink Panthers, too. Radical women's groups, even 'lesbian separatists' who wanted to abolish men altogether! And the Yippies. Anyone ever hear of the Yippies?"

"Didn't they levitate the Pentagon?" I said. I'd once seen a documentary about this.

She laughed. "I forgot about that, but yes, that was them! Yippies were like very political hippies, but they weren't serious the way we think of politics these days. They were very playful. Pranksters. They threw money into the New York Stock Exchange. They circled the Pentagon with hundreds of protestors and said a magic spell that was supposed to levitate it. They invented a fictional kind of LSD that you could spray onto people with squirt-guns and shot each other with it and pretended to be stoned. They were funny and they made great TV -- one Yippie, a clown called Wavy Gravy, used to get hundreds of protestors to dress up like Santa Claus so that the cameras would show police officers arresting and dragging away Santa on the news that night -- and they mobilized a lot of people.

"Their big moment was the Democratic National Convention in 1968, where they called for demonstrations to protest the Vietnam War. Thousands of demonstrators poured into Chicago, slept in the parks, and picketed every day. They had lots of bizarre stunts that year, like running a pig called Pigasus for the presidential nomination. The police and the demonstrators fought in the streets -- they'd done that many times before, but the Chicago cops didn't have the smarts to leave the reporters alone. They beat up the reporters, and the reporters retaliated by finally showing what really went on at these demonstrations, so the whole country watched their kids being really savagely beaten down by the Chicago police. They called it a 'police riot.'

"The Yippies loved to say, 'Never trust anyone over 30.' They meant that people who were born before a certain time, when America had been fighting enemies like the Nazis, could never understand what it meant to love your country enough to refuse to fight the Vietnamese. They thought that by the time you hit 30, your attitudes would be frozen and you couldn't ever understand why the kids of the day were taking to the streets, dropping out, freaking out.

"San Francisco was ground zero for this. Revolutionary armies were founded here. Some of them blew up buildings or robbed banks for their cause. A lot of those kids grew up to be more or less normal, while others ended up in jail. Some of the university dropouts did amazing things -- for example, Steve Jobs and Steve Wozniak, who founded Apple Computers and invented the PC."

I was really getting into this. I knew a little of it, but I'd never heard it told like this. Or maybe it had never mattered as much as it did now. Suddenly, those lame, solemn, grown-up street demonstrations didn't seem so lame after all. Maybe there was room for that kind of action in the Xnet movement.

I put my hand up. "Did they win? Did the Yippies win?"

She gave me a long look, like she was thinking it over. No one said a word. We all wanted to hear the answer.

"They didn't lose," she said. "They kind of imploded a little. Some of them went to jail for drugs or other things. Some of them changed their tunes and became yuppies and went on the lecture circuit telling everyone how stupid they'd been, talking about how good greed was and how dumb they'd been.
