That sight made my blood run hot. It was a beautiful cool night and we were about to party, really party, party like there was no tomorrow. "Eat drink and be merry, for tomorrow we die."

Without saying anything we both broke into a trot. There were lots of cops, with tense faces, but what the hell were they going to do? There were a lot of people in the park. I'm not so good at counting crowds. The papers later quoted organizers as saying there were 20,000 people; the cops said 5,000. Maybe that means there were 12,500.

Whatever. It was more people than I'd ever stood among, as part of an unscheduled, unsanctioned, illegal event.

We were among them in an instant. I can't swear to it, but I don't think there was anyone over 25 in that press of bodies. Everyone was smiling. Some young kids were there, 10 or 12, and that made me feel better. No one would do anything too stupid with kids that little in the crowd. No one wanted to see little kids get hurt. This was just going to be a glorious spring night of celebration.

I figured the thing to do was push in towards the tennis courts. We threaded our way through the crowd, and to stay together we took each other's hands. Only staying together didn't require us to intertwine fingers. That was strictly for pleasure. It was very pleasurable.

The bands were all inside the tennis courts, with their guitars and mixers and keyboards and even a drum kit. Later, on Xnet, I found a Flickr stream of them smuggling all this stuff in, piece by piece, in gym bags and under their coats. Along with it all were huge speakers, the kind you see in automotive supply places, and among them, a stack of...car batteries. I laughed. Genius! That was how they were going to power their stacks. From where I stood, I could see that they were cells from a hybrid car, a Prius. Someone had gutted an eco-mobile to power the night's entertainment. The batteries continued outside the courts, stacked up against the fence, tethered to the main stack by wires threaded through the chain-link. I counted -- 200 batteries! Christ! Those things weighed a ton, too.

There's no way they organized this without email and wikis and mailing lists. And there's no way people this smart would have done that on the public Internet. This had all taken place on the Xnet, I'd bet my boots on it.

We just kind of bounced around in the crowd for a while as the bands tuned up and conferred with one another. I saw Trudy Doo from a distance, in the tennis courts. She looked like she was in a cage, like a pro wrestler. She was wearing a torn wife-beater and her hair was in long, fluorescent pink dreads down to her waist. She was wearing army camouflage pants and giant gothy boots with steel over-toes. As I watched, she picked up a heavy motorcycle jacket, worn as a catcher's mitt, and put it on like armor. It probably was armor, I realized.

I tried to wave to her, to impress Ange I guess, but she didn't see me and I kind of looked like a spazz so I stopped. The energy in the crowd was amazing. You hear people talk about "vibes" and "energy" for big groups of people, but until you've experienced it, you probably think it's just a figure of speech.

It's not. It's the smiles, infectious and big as watermelons, on every face. Everyone bopping a little to an unheard rhythm, shoulders rocking. Rolling walks. Jokes and laughs. The tone of every voice tight and excited, like a firework about to go off. And you can't help but be a part of it. Because you are.
