More than 100 people were arrested at weekend rave in Northern California, mostly for drug offenses and public drunkenness.
Mountain View Police Lt. Chris Hsiung says most of those arrested at the Beyond Wonderland concert were charged with furnishing or using illegal drugs such as Ecstasy, LSD and the stimulant GHB.
The San Jose Mercury News reports police also arrested some people for drunkenness. Others were wanted on outstanding warrants.
Hsiung says no major medical emergencies were reported at the concert at Shoreline Amphitheater, where about 40,000 electronic music fans gathered over two days. On the first day of the rave, there were no arrests, but that number jumped to at least 67 by Sunday afternoon. Mountain View police had stepped-up patrols for the weekend.
Many said they came just for fun - not to get high and into trouble.
"We're just really excited to go in there and dance and listen to all of the music," a man named Curtis said. "It's going to be great."
A man and woman, Alex and Sierra, also said they came to the rave together to just have a goog time.
"I've been going on-and-off for the past like four years, so it's sort of become a lifestyle for us, so it's really cool," Alex said. "We like it a lot."
The Cow Palace in Daly City banned raves three years ago after two concert-goers died from drug overdoses.
