There were many types of people wandering the crowd at Wakarusa. You could see everything from fratty-looking people to dreaded hippies to people covered in mud to these folks here.
The first guy and gal were during The Disco Biscuits on Saturday night. The other two girls were at STS9 (Sound Tribe Sector 9) on Sunday night. If I'd had more recording space, the girl at the end was particularly good as she could do really nice tricks while also dancing well to the music. She even did a couple back bends while spinning the flame towards herself in a manner similar to that seen in the second clip of the second girl.
