Has anyone worked at the Portland International Raceway ever?

For finacial reasons I wont be able to finish the school year, I'm in college right now (freshmen), and am looking for a job for the spring and summer. I don't live to far from the Portland International Raceway and was wondering if anyone had worked there before. I'm looking at just low end stuff. If you can help please do.
Would I have to be a member of the SCCA to get a job?

Thanks in advance!!
