From the transcript of the Chicago Seven trial:

Abbie Hoffman:  “I live in Woodstock Nation.”
Defense attorney:  “Will you tell the court and the jury where it is?”
Hoffman:  “Yes, it is a nation of alienated young people. We carry it around with us as a state of mind, in the same way the Sioux Indians carry the Sioux Nation with them…”

I’m with Abbie. I don’t really identify with a geographic location.
