Wasn't there a $30 SCCA trial membership somewhere?

Also, I'm looking at the SF. CA Champ Rnd 3 and 5 on 3/20 and 3/27 (oakland). Are these the one I start at? Do I get to start in the "novice" class?

My car falls under HS under STS, right?

How much time am I looking at for the 3/20,27 days? (Like when do I arrive to when do I get to go home; got a family...)
