I vaguely remember 2 decks, maybe there was 3? Also, a huge BOUNCE sign (individual letters, all different sizes and fonts, and different colors, looked to be made of plywood), and they were circling outer playa at sunrise one of the last mornings (either sunday or monday). Their music was warm, happy, disco-wy, a perfect sunrise party!
If I could find whose camp that bus parks with, I'd try to set up my camp next to them
)) I loved their music, I'd listen to that all day long.
