Since 2003 I've been putting on this annual event that starts in the SF bay Area and winds up camping up in Humboldt/Mendocino or Lake County. We usually limit it to 5 entrants, but this year there seemed to be enough interest that I'm opening it for 10 and with a little over 3 weeks between now and then- there are still 3 slots open.
Rather than repeating a whole bunch of stuff in both forums, I'd like to point you to the thread on i-club,
post # 20 explains the basic format
It is always a great time, I've made several great friends through this- if you enjoy taking your WRX out and running it like it was built to be run, chances are you won't be disappointed.
If you are interested either check in there on i-club or contact me directly at email@example.com
