"MID-MORNING ON SATURDAY, Berkeley people laid what looked like a thousand tabs of sunshine acid on the Angels-- sunshine: it had a lot of speed in it--and this was being dispersed both at the Angels' bus thirty yards uphill and on the stage. At one point, 500 reds were scattered on the front portion of the stage. The Angels were downing tabs of acid/speed and reds in huge gulps of Red Mountain wine. The more they took, the more fighting there was."
