Michael, do you already know somebody in the club, or are you just interested in joining?
Are you more interested in desert races, or grand prixs or both?
I recommend coming out to an upcoming event and pitting/camping with us. That way you can get to know some people and see if it's a group you might be interested in.
Our club event is coming up at the end of February. So we'll be out in the desert on February 18 to set up our course, and then our race is the weekend of Feb 25-26. If you are able to come out for one or both of those events, it is the best way to meet nearly all of the people in the club.
