For those in Socal this is a great way to get seat time. They have events every Tuesday night which cost $20 a session with a total of three sessions. Usually a session is 3 runs of 3 ~50 second laps so it is decent seat time for the cost. Here is a link to the site:

The track is pretty tight and roll bars are required. As long as you dont go to crazy you should be fine. Post up when you plan to go!
