As a result of being mentioned in Jeff's article, I received a call from a guy interested in getting started as a hill climber. I referred him to this site and to the SCCA site for information.
After our conversation, I decided to go see what I had done. There is indeed a link to Time Trials rules from this web site, but they're the 2005 version. On the SCCA site you can get a copy of the 2006 Time Trials rules.
What does one do if he or she plans to compete in 2007?
